31 Best SMS Marketing Tools in 2026
SMS marketing platforms range from developer-focused APIs like Twilio and Telnyx to turnkey ecommerce solutions like Postscript and Attentive, plus peer-to-peer organising tools used by nonprofits and political campaigns. This guide covers all major categories: CPaaS infrastructure, self-serve marketing platforms, ecommerce-native SMS, and mission-driven tools. Pricing in this guide was verified in March 2026 directly from vendor pricing pages and recent user reviews.
Twilio
Twilio is the dominant CPaaS (Communications Platform as a Service) provider, used by companies like Airbnb, Uber, and Lyft to power programmable SMS, voice, and WhatsApp at scale. It operates on a pure pay-as-you-go model: outbound SMS in the US costs $0.0079 per message, inbound is $0.0075, with additional A2P 10DLC carrier fees on top. Twilio's acquisition of SendGrid added email, and its Flex and Frontline products add contact center and CRM-adjacent functionality. The platform is entirely API-first — there is no ready-made campaign builder, so teams without developers will need third-party tools to run marketing programs.
- • Programmable Messaging API: REST API for sending/receiving SMS, MMS, and WhatsApp in 180+ countries with delivery webhooks and message status callbacks.
- • A2P 10DLC support: Built-in brand and campaign registration tooling for US A2P compliance, including registration status tracking in the console.
- • SendGrid integration: Twilio-owned email platform enables unified transactional email and SMS pipelines through shared APIs and credentials.
- • Twilio Flex: A programmable cloud contact center that allows teams to build custom agent desktops with SMS, voice, and WhatsApp channels.
- • RCS support: Twilio supports Rich Communication Services in select regions for branded, interactive messages beyond standard SMS.
Twilio is the right choice for engineering teams that need maximum flexibility, global reach, and a battle-tested API backbone. It is not the right choice if you need a marketer-friendly interface or want to control messaging costs at scale without negotiating volume deals. For most non-developer use cases, a purpose-built SMS marketing platform will deliver faster time-to-value at lower total cost.
Klaviyo SMS
Klaviyo is an ecommerce CRM and marketing automation platform used by over 169,000 businesses. In early 2025 it shifted to active-profile-based billing, meaning you pay based on total stored contacts rather than email volume — a change that caught many existing customers off guard with cost increases. The Email + SMS plan starts at $35/month for up to 500 active profiles and includes 1,250 SMS/MMS credits. SMS credits are separate from email: US SMS costs approximately $0.01 per message. Klaviyo's deep Shopify integration, predictive analytics, and 350+ native integrations make it the dominant email-first SMS solution for mid-market DTC brands.
- • Unified profiles: Every contact's email, SMS, push, and purchase history lives in one profile, enabling cross-channel segmentation and suppression in real time.
- • Predictive analytics: AI models predict customer lifetime value, churn risk, and next order date, available from the Email plan tier upward.
- • 350+ integrations: Native connections to Shopify, WooCommerce, Magento, Salesforce, and most major ecommerce and CRM stacks.
- • Multi-channel A/B testing: Run split tests across email and SMS variants simultaneously from a single experiment setup.
- • SMS Smart Opt-In: Collects double opt-in via a keyword-triggered confirmation flow to meet TCPA and carrier compliance requirements.
Klaviyo SMS makes the most sense for brands already invested in Klaviyo email who want to add text without introducing a second platform. New ecommerce brands evaluating SMS from scratch should compare total cost at their expected list size — for lists above 10,000 profiles, Klaviyo's active-profile billing frequently results in higher monthly costs than Omnisend or Attentive at comparable feature levels.
Attentive
Attentive is an AI-powered SMS and email marketing platform built for enterprise ecommerce, with clients including brands across retail, apparel, food and beverage, and entertainment. It has raised over $864 million in cumulative funding as of mid-2025. Unlike most SMS platforms, Attentive does not publish transparent pricing — all plans are custom-quoted based on subscriber count, message volume, and AI feature selection. Based on publicly available contract data, quarterly minimums typically run $2,000–$3,000, which breaks down to roughly $667–$1,000/month before a single text is sent. Contracts are 6–12 months in length. Attentive's two-tap signup unit is a proprietary subscriber acquisition tool that collects consent with a single tap on mobile.
- • Two-tap signup: Proprietary mobile opt-in unit that pre-fills subscriber data from the device, delivering industry-claimed higher conversion rates versus standard web forms.
- • AI Journeys: Machine learning models that determine optimal send times, message cadence, and content variants per individual subscriber.
- • RCS support: Attentive launched an RCS Hub in 2025 enabling rich-format branded messages with images, carousels, and action buttons.
- • Real-time behavioral triggers: Sends messages based on site actions, cart events, and purchase signals with sub-minute latency.
- • 100+ ecommerce integrations: Native connections to Shopify, Salesforce, Klaviyo, Yotpo, Recharge, and most major loyalty and review platforms.
Attentive earns its premium when SMS drives 15%+ of total revenue and monthly turnover exceeds $200k — the white-glove service and AI-driven personalization justify the quarterly commitment at that scale. For everyone else, the minimum spend requirements and contract terms create more risk than reward.
Postscript
Postscript is an SMS marketing platform built exclusively for Shopify, used by over 10,000 Shopify merchants. Unlike Klaviyo or Attentive, its entire product roadmap is SMS-first. The platform uses usage-based billing: the Starter plan is free with a $49/month minimum spend, Growth is $100/month, and Professional is $500/month, each with decreasing per-message rates. US SMS on the Starter plan costs $0.009/message (reduced from $0.015 at launch), while Growth drops to $0.008 and Professional removes the per-message premium. Postscript does not charge for incoming messages. A dedicated short code from carriers costs an additional $750/month, passed through at cost with no markup.
- • Shopify-native data sync: Product catalog, inventory levels, order history, and customer segments sync in real time — no Zapier required.
- • Infinity Testing: AI-powered automation variant testing that continuously runs hundreds of on-brand message variants to identify top performers.
- • Shopper AI agent: An always-on conversational SMS shopping assistant that answers product questions and drives sales without agent involvement.
- • CashBack (via Fondue): A smart coupon alternative that gives subscribers store credit rather than discount codes, protecting margins.
- • Usage-based billing: No credit pre-purchase required — brands pay after sending, with full per-day, per-carrier, per-message-type billing transparency.
Postscript is the strongest SMS-only choice for Shopify merchants who want to keep their email platform separate and need a platform that deeply understands ecommerce. Its usage billing, no-markup carrier fees, and Shopify data depth are genuine competitive advantages. Non-Shopify brands should look elsewhere.
SimpleTexting
SimpleTexting is owned by Sinch (acquired 2021) and serves thousands of businesses across retail, healthcare, education, and nonprofits. Its credit-based pricing starts at $29/month for 500 texts via toll-free number, or $39/month for a local number, with all features — including automations, API access, AI Assist, and unlimited keywords — included on every plan regardless of tier. Unused credits roll over for one month. The platform earns strong marks for customer support (7 days/week by phone, chat, and email) and is consistently ranked among the top tools for small businesses by business.com and Capterra.
- • All-inclusive plans: Every tier — including the entry-level $29/month plan — includes automations, unlimited keywords, API access, MMS, and AI Assist message drafting.
- • Rollover credits: Unused credits carry over one month, which is particularly useful for seasonal businesses or irregular senders.
- • Custom integrations: SimpleTexting offers a $49/month sync service for Constant Contact and Wix, and custom-built integrations starting at a $1,000 setup fee for higher-tier plans.
- • Text-to-landline: Existing landline or VoIP numbers can be text-enabled for two-way conversations without changing the phone number.
- • Team inbox: Multiple users can manage conversations with assignment, tagging, and internal notes.
SimpleTexting is a genuinely good choice for small businesses that want every feature on day one without negotiating tiers or upgrades. The per-user add-on cost is the main friction point for growing teams — evaluate carefully if you need more than two or three people in the platform.
TextMagic
TextMagic is a UK-headquartered business SMS platform that has operated since 2001. It uses a pay-as-you-go pricing model with no monthly subscriptions required: US SMS costs $0.049 per message, with credits that never expire. For higher-volume senders, monthly plans start at $99/month and include bundled credits at a discounted rate. TextMagic covers SMS, MMS, email-to-SMS, two-way chat, and scheduling across 190+ countries. In 2024–2025 the company expanded its platform to include omnichannel inbox features and SOC 2 compliance for enterprise customers.
- • Email to SMS: Send SMS directly from any email client by addressing to [number]@textmagic.com — no dashboard login required.
- • Global coverage: Supports outbound SMS to 190+ countries and two-way messaging in over 40 markets with local virtual numbers.
- • Sub-accounts: Create team member sub-accounts with role-based permissions and shared or separate contact lists.
- • API and Zapier integration: REST API supports custom SMS workflows; Zapier connector links with CRM, scheduling, and ecommerce platforms.
- • GDPR and HIPAA compliance: SOC 2 Type II certified with end-to-end encryption and audit trail support for regulated industries.
TextMagic is best suited to businesses that send internationally or send sporadically in the US. For any US-only brand sending more than 1,000 messages per month on a regular schedule, a subscription-based platform will deliver a lower effective cost per message.
EZ Texting
EZ Texting is one of the longest-running US SMS marketing platforms, founded in 2006 and serving businesses across retail, education, churches, nonprofits, and home services. It offers four published plans: Launch ($25/month billed annually), Boost ($75/month), Scale ($125/month), and Enterprise ($3,000/month for short codes). Every plan includes 500 monthly credits, with additional credits available at rates ranging from $0.04 per message on Launch to $0.01 per message on Enterprise. All plans include AI Compose, AI Reply, signup forms, QR codes, and an unlimited keyword count. In late 2025, EZ Texting added automated Workflow triggers for abandoned cart and event reminders.
- • AI Compose and AI Reply: Draft outbound campaigns with AI assistance and auto-suggest replies to incoming customer messages from the team inbox.
- • MMS Edge: Integrated Shutterstock image library and editor for creating rich visual campaigns without external design tools.
- • Keyword opt-ins: Unlimited keywords on all paid plans for subscriber list building and automated welcome flows.
- • Workflow automation: Visual automation builder with templates for abandoned cart recovery, appointment reminders, and feedback collection.
- • Integrations: Native connections to HubSpot, Salesforce, Constant Contact, and Zapier; all plans support the open API.
EZ Texting is particularly well-suited for churches, nonprofits, and small brick-and-mortar businesses that need a polished, easy-to-use platform with strong visual content tools. Growing teams should model user seat costs carefully, as the $10/user add-on can quickly make the effective monthly price significantly higher than competitors that include unlimited users.
SlickText
SlickText has operated since 2012 and consistently earns the highest user satisfaction scores among self-serve SMS platforms on G2 and Capterra. Pricing starts at $29/month for 500 credits and scales to $1,999/month for 100,000 credits, with nine published tiers in between. Every plan — including the $29 entry tier — includes unlimited users, unlimited contacts, rollover credits, all automation features, and every integration. The platform explicitly price-matches any SimpleTexting standard plan. One-on-one onboarding sessions are included from $129/month and above, and a dedicated Customer Success Manager is assigned at 50,000 credits/month.
- • Unlimited users on every plan: No per-seat fees at any tier — a growing team can add members without incremental cost.
- • Workflows: Visual drag-and-drop automation builder supporting multi-branch journeys triggered by subscriber data, keywords, or behavior.
- • Website popups: Native popup builder for SMS opt-in collection on any website, without requiring a separate tool.
- • Dynamic segments: Real-time audience segments built from contact data and behavior, automatically updated as conditions change.
- • 15+ native integrations: Shopify, HubSpot, Salesforce, Mailchimp, Klaviyo, and others — approximately 2.5x more native integrations than EZ Texting.
SlickText is the best self-serve SMS platform for teams of more than two people who want a fully-featured platform without seat-based pricing surprises. For solo users or very small teams, it competes evenly with SimpleTexting — the unlimited user policy becomes a clear win as the team scales beyond three people.
Textedly
Textedly is a US-based SMS marketing platform with 14 published pricing tiers from Basic ($29/month with 1,000 texts) to Champion ($3,599/month). Following an August 2025 price increase, the entry-level Bronze plan moved to $49/month for 1,200 texts (with 20% bonus texts on annual billing). All plans include free incoming messages, unlimited contacts, picture messaging (MMS), text-to-pay via Stripe, Google Business Reviews integration, an omnichannel inbox, and AI text composer. Annual subscribers receive 20% more monthly messages than monthly billing. The platform has a 14-day free trial with no credit card required.
- • Text-to-pay: Embedded Stripe payment links in SMS messages with a 2.9% + $0.30 transaction fee — available on Plus plan and above.
- • Google Reviews integration: Trigger review request texts after purchase, with responses tracked in the Textedly inbox.
- • 300-character single messages: Unlike standard 160-character SMS limits, Textedly allows up to 300 characters to count as one text.
- • AI Voice Agents: Textedly introduced AI voice agents in 2025 that handle inbound calls with human-like conversation on any subscribed number.
- • Drip campaigns: Set automated message sequences triggered by keyword opt-ins or subscriber data events.
Textedly is a solid option for straightforward bulk SMS at a reasonable per-message rate, especially for real estate, small retail, and service businesses that want text-to-pay built in. The recent price increase and keyword restrictions make it less compelling than SlickText or SimpleTexting for growing teams. Always read the cancellation terms before purchasing annual plans.
Salesmsg
Salesmsg is a two-way business texting platform built around CRM integration — it natively integrates with HubSpot, ActiveCampaign, Infusionsoft/Keap, Pipedrive, and Zapier. Pricing starts at $25/month for 500 credits with flexible month-to-month billing and a 14-day free trial. Plans scale up to 50,000+ credits/month, with annual plans saving approximately 20% versus monthly. The platform includes shared inboxes, a mobile app, landline texting, short code texting, call forwarding, and MMS. In contrast to purely marketing-focused tools, Salesmsg is designed for sales reps to conduct personalized 1:1 conversations at scale.
- • HubSpot native integration: Send and receive texts directly inside HubSpot contact records, with bidirectional sync of message history and contact activity.
- • Shared inbox: Multiple team members can view, reply to, and assign incoming conversations from a single inbox with internal note threading.
- • Landline texting: Text-enable any existing US landline or VoIP number, allowing customers to reply to the number they already know.
- • Call forwarding: Forward calls from the Salesmsg number to a mobile or office phone, so the same number handles voice and text.
- • Graduated pricing: Per-credit cost decreases as volume increases, with transparent breakdowns in the billing portal.
Salesmsg is the right pick for sales teams that live in HubSpot and want texting to feel like a native HubSpot feature rather than a bolt-on. For pure mass-marketing campaigns, a platform like SlickText or SimpleTexting will deliver better per-message economics and a more campaign-oriented UI.
Sakari
Sakari is a cloud-based SMS marketing platform founded in 2017 that is the original certified HubSpot SMS partner. Monthly plans start at $25/month and include one free dedicated US, Canadian, UK, or French number, with unlimited users and contacts on all plans. The $25 Starter plan covers up to approximately 820 US SMS messages (based on a $0.0304/segment rate), with per-message rates decreasing on higher tiers. Sakari also supports MMS (priced at a $0.02 premium per segment), WhatsApp, and voice from a single platform, and covers 30+ countries globally. Credits roll over for up to 90 days on active paid accounts.
- • HubSpot certified integration: The original HubSpot SMS partner — triggers messages from HubSpot workflows, syncs reply history to contact timelines without middleware.
- • Multi-channel from one platform: SMS, MMS, WhatsApp, and voice calls all managed from a single inbox and number.
- • Drip campaigns and automation: Visual campaign builder for automated sequences triggered by time delays, contact field values, or webhook events.
- • Branch accounts: Multi-location businesses and agencies can manage multiple client accounts under one Sakari master account.
- • Global messaging: Sends to 30+ countries with local virtual number support in US, Canada, UK, France, and others.
Sakari is the top choice for teams standardised on HubSpot who need SMS triggers to fire from workflow automation without developer work. The platform depth has historically lagged behind its integration quality — the 2025 platform beta should be reviewed before signing up if UI sophistication matters to your team.
Bird
Bird (formerly MessageBird) is a Netherlands-headquartered omnichannel CRM and messaging platform that rebranded in February 2024, simultaneously slashing SMS prices by up to 90% to compete with Twilio. Founded in 2011, Bird powers 40% of global commerce email according to its own figures and serves over 15,000 enterprise customers including Uber, DoorDash, and Heineken. Pricing is usage-based with volume tiers — US SMS costs approximately $0.0008 per message (after the 90% reduction), making it among the lowest published API rates in the market. The free account gives access to test credits with no credit card required. Bird bundles SMS, email, WhatsApp, and a visual flow builder into one CRM platform.
- • Omnichannel flow builder: Visual drag-and-drop tool for building customer journeys that span SMS, email, WhatsApp, Facebook Messenger, and push notifications.
- • Global carrier network: Direct routes to 220+ countries with failover delivery and real-time delivery receipts.
- • Email + SMS + WhatsApp: A unified platform for all three channels under a single API and dashboard — reducing tool sprawl for global messaging programs.
- • Bird AI: Generative AI assistant for drafting email copy, building landing pages, and planning campaigns from within the platform.
- • Conversational commerce: Supports in-thread purchasing and support escalation flows across WhatsApp and SMS.
Bird's pricing reset makes it genuinely competitive for high-volume global SMS when cost-per-message is the primary driver. Teams that need stability, mature documentation, or a large developer community should still evaluate Twilio and Sinch alongside Bird before committing.
Vonage
Vonage (now part of Ericsson) is a Communications APIs platform providing SMS, voice, video, verification, and WhatsApp through a unified REST API. Its SMS API covers 200+ countries and supports long codes, toll-free, and short codes. US outbound SMS pricing is not published on a flat rate — Vonage uses destination-based pricing visible in the account dashboard, with US rates typically in the $0.006–$0.009 range depending on message type and number. Inbound SMS to US toll-free numbers costs €0.0057. Vonage differentiates from pure CPaaS competitors through its contact center products (Vonage Contact Center, Vonage Business Cloud) and deep Salesforce integration.
- • Messages API: Unified API for SMS, MMS, RCS, WhatsApp, Facebook Messenger, and Viber — single endpoint for all messaging channels.
- • Dispatch API: Omnichannel fallback logic — automatically retries undelivered messages on an alternative channel (e.g., SMS fallback to WhatsApp).
- • Vonage AI Studio: No-code builder for conversational AI flows that span voice, SMS, and chat without writing custom code.
- • Verify API: Two-factor authentication API with automatic channel selection (SMS, voice, email) and a flat charge only for successful verifications.
- • Extensive SDKs: Official libraries for Node.js, Python, Java, Ruby, PHP, .NET, and Go with extensive sample applications.
Vonage is the right API platform for enterprise teams already using Salesforce or Vonage Business Cloud who need unified voice, SMS, and AI capabilities under an Ericsson-backed SLA. Pure SMS or pure CPaaS use cases are usually better served by Twilio, Telnyx, or Plivo.
Sinch
Sinch is a Swedish-listed CPaaS company that has grown substantially through acquisitions — including SimpleTexting (2021), MessageMedia, and Mailgun. Its core API platform provides SMS, MMS, RCS, WhatsApp, and voice with direct connections to 600+ operators worldwide. For self-serve users, the Sinch Engage (formerly MessageMedia) product starts at $49/month for 1,000 SMS credits. The SMS API charges approximately $0.0085/message in the US, slightly above Telnyx but below Twilio. Sinch's 2025 RCS capabilities and direct carrier relationships make it a strong choice for enterprise brands rolling out RCS alongside SMS.
- • Direct carrier connections: 600+ direct operator relationships across 190+ countries eliminate aggregator hops and reduce latency for global enterprise deployments.
- • RCS support: Sinch is a leading RCS delivery partner for enterprise brands building rich interactive message campaigns in 2025–2026.
- • Sinch Engage multi-channel: Bundles SMS, WhatsApp, Instagram, and Facebook Messenger management under one team inbox with subaccount support.
- • Verification API: OTP and phone number verification products separate from the core messaging API with per-verified-user billing.
- • Compliance toolkit: 10DLC registration, toll-free verification, and carrier compliance tooling built into the Sinch platform dashboard.
Sinch is the strongest enterprise choice for brands that need direct carrier infrastructure, global scale, and a roadmap that includes RCS as a first-class channel. For self-serve marketing teams, Sinch Engage competes with SimpleTexting and Textedly but its credit expiration policy is a notable downside.
Plivo
Plivo is a developer-first CPaaS platform founded in 2011, offering voice, SMS, and WhatsApp APIs across 220+ countries with outbound US SMS starting at $0.0045–$0.0055 per message — approximately 40–45% cheaper than Twilio. It offers a $5 free credit on signup for API testing. In 2024–2025, Plivo expanded beyond pure CPaaS with Plivo CX (an omnichannel contact center product starting at $29/user/month) and an AI Agent Platform for automated voice and SMS interactions. Phone numbers start at $0.50/month for local US long codes versus Twilio's $1.00/month.
- • Competitive pricing: US outbound SMS at $0.0045–$0.0055 is among the lowest in the established CPaaS market, with US long codes at $0.50/month versus Twilio's $1.00/month.
- • Voice calling: Outbound calls from $0.0035/minute in the US — lower than both Twilio ($0.014/min) and Vonage in most markets.
- • Plivo CX: Omnichannel contact center suite with voice, SMS, and WhatsApp channels, starting at $29/user/month for voice-only configurations.
- • AI Agents: SMS and voice AI agents at $0.09/execution (SMS/WhatsApp) or $0.05/minute (voice) for automated customer interactions.
- • SDKs for 7 languages: Python, Node.js, Java, PHP, Ruby, Go, and .NET with REST API documentation comparable to Twilio in coverage.
Plivo delivers genuine CPaaS-grade infrastructure at 40–45% lower cost than Twilio for SMS and voice. The cost savings are most meaningful at high volume — above 500,000 messages/month. Teams that need responsive support or are new to CPaaS will find Twilio or Telnyx's support models less frustrating during initial integration.
Bandwidth
Bandwidth is a Raleigh-based CPaaS company that is unique among API providers in owning its own nationwide all-IP voice network — it is not reselling carrier capacity. This means Bandwidth customers access the same infrastructure that powers Google, Microsoft, Zoom, and Ring Central. US SMS messaging starts at $0.004 per message — one of the lowest published API rates in the US market. Voice calling starts at $0.0055/minute. The platform is exclusively API-first; there is no self-serve marketing dashboard or pre-built campaign builder.
- • Owned carrier network: Bandwidth owns its US network infrastructure, not leasing from a tier-1 carrier — this provides direct route control, lower latency, and SLA-backed delivery.
- • Messaging API: Supports SMS, MMS, toll-free A2P, short codes, and group messaging with delivery receipts and real-time status callbacks.
- • Emergency 911 API: Nationwide 911 call routing capability for platforms that handle emergency communications — unique among CPaaS providers.
- • RCS capabilities: Bandwidth deployed RCS agent provisioning for enterprise customers in 2025 with direct carrier connectivity.
- • 52 million US phone numbers: Access to a large pool of local, toll-free, and vanity numbers for direct provisioning.
Bandwidth is the right infrastructure choice for enterprise software companies that need maximum control, carrier-grade reliability, and the lowest US messaging rates — particularly those whose products touch emergency communications or mission-critical transactional messages. The support limitations and lack of any marketing UI make it unsuitable for teams without dedicated engineering resources.
Telnyx
Telnyx is a US CPaaS provider that operates its own private fiber network — a key differentiator from aggregator-based competitors. US SMS costs $0.004 per message for both inbound and outbound (roughly half Twilio's rate), with no monthly minimums and automatic tiered discounts above 100 million messages/month. 10 messages per second throughput per long code is 10x Twilio's default (1 MPS), enabling faster high-volume campaigns. All Telnyx accounts include 24/7 live chat and phone support with actual engineers — included in the standard plan without an additional fee. The platform covers 180+ countries.
- • Private fiber network: Telnyx routes traffic over owned fiber infrastructure rather than leased capacity, reducing latency and improving delivery reliability.
- • 10 MPS throughput per long code: Default 10x higher throughput than Twilio's 1 MPS per long code — critical for time-sensitive bulk sends.
- • Mission Control Portal: Self-service dashboard for number provisioning, messaging profile management, real-time traffic monitoring, and SIP debugging.
- • All-channel support: SMS, MMS, RCS, voice, fax, WhatsApp, and SIP trunking from a single platform and API credential set.
- • 24/7 live engineer support: Free phone and chat support staffed by engineers — not tier-1 scripts — on all accounts including pay-as-you-go.
Telnyx is the most compelling Twilio alternative for cost-conscious engineering teams that send above 500,000 messages/month and need reliable 24/7 technical support. The combination of half-price messaging, 10x throughput per number, and free live engineer support is a differentiation few CPaaS providers can match.
ClickSend
ClickSend is an Australian-headquartered business communications platform founded in 2009, now part of Sinch (following the MessageMedia acquisition). It supports over 90,000 users across 200+ countries and covers SMS, MMS, email, voice, fax, and traditional post in one dashboard. US SMS pricing starts at $0.0226 per message for under 5,000 monthly messages, dropping to $0.0081 for 150,000+. The pay-as-you-go model has no monthly subscription requirement. ClickSend is notable among SMS platforms for its direct mail capability — businesses can send printed postcards and letters triggered by customer events.
- • Multi-channel from one platform: SMS, MMS, email, voice-to-text calls, fax (for regulated industries), and physical printed mail all available with a single API and credit balance.
- • Direct mail: Trigger printed postcards, letters, and A4 documents from the ClickSend dashboard or API — useful for real estate, healthcare, and financial services follow-up.
- • Zapier and Power Automate integration: 1,000+ pre-built connectors to CRM and ecommerce platforms without custom code.
- • Bulk SMS campaigns: Upload contact lists via CSV, segment by custom fields, and schedule campaign delivery with delivery reports.
- • Global delivery: Routes to 200+ countries with transparent per-country pricing in the dashboard pricing calculator.
ClickSend is uniquely positioned for businesses that need physical direct mail alongside SMS — no other platform in this list supports that combination at the self-serve level. For pure SMS marketing, the per-message rate at low volume is higher than most alternatives, making ClickSend most valuable to teams that genuinely use multiple channels.
SMSAPI
SMSAPI is a Polish-headquartered bulk SMS platform operated by LINK Mobility, one of the largest A2P messaging companies in Europe. It serves over 7,000 customers across business, government, and ecommerce sectors in Europe and globally. The platform operates on a prepaid credit model with no contracts, no setup fees, and no hidden costs. Pricing varies by destination country — EU markets are priced differently from the US. SMSAPI supports SMS API integration, a web panel for manual campaigns, a mobile app, two-way messaging, sender ID customization, and delivery reports. It includes official integrations with CMS, CRM, and ecommerce platforms popular in European markets.
- • EU-native platform: Operated by LINK Mobility, with data centers and carrier relationships optimised for European messaging compliance and delivery.
- • REST API and SMPP gateway: Both REST and SMPP protocols supported — ideal for high-throughput enterprise integrations that require direct carrier protocol access.
- • Sender ID customization: Set alphanumeric sender names for outbound messages in countries that support customised sender IDs.
- • Two-way messaging: Supports two-way SMS conversations through virtual numbers available in supported countries.
- • Zapier integration: Connects SMSAPI with 5,000+ apps without custom development work.
SMSAPI is a strong choice for European businesses that need a reliable, compliance-first SMS API with no monthly commitment and genuine LINK Mobility carrier infrastructure behind the delivery. US-primary businesses will find better pricing and support from US-headquartered platforms.
BulkSMS
BulkSMS is a South Africa-headquartered messaging platform with over 20 years of operation, particularly strong in African and emerging market delivery. It offers web-based bulk SMS campaigns, a REST API, and integrations for websites and applications, across 220+ countries. Pricing is prepaid and credit-based with no monthly subscription fee — credits are purchased in packs and used at varying per-message rates depending on destination country. BulkSMS supports two-way messaging, delivery reports, group messaging, and contact list management. The platform has a simple, clean interface oriented toward high-volume batch sending rather than automated drip campaigns.
- • Direct operator connections: BulkSMS maintains direct routes to operators in African, European, and emerging market countries where aggregator-based providers often have poor delivery.
- • Web App: Upload contact lists via CSV, compose messages with personalisation merge fields, and schedule campaigns without any API integration.
- • REST API: Full-featured REST API for programmatic bulk sending, status polling, and reply handling.
- • Group texting: Manage named contact groups and send to multiple groups simultaneously with automatic deduplication.
- • Firewall integrations: Used by several customers specifically for automated SMS alerts from network monitoring and firewall systems — a niche use case well supported by the platform.
BulkSMS is the right choice for businesses with specific needs in African or emerging market SMS delivery, or for IT operations teams needing a simple, reliable batch-send gateway for automated alerts. For US or European marketing use cases, more feature-rich platforms deliver better automation and analytics at comparable price points.
Trumpia
Trumpia has been operating since 2010 and differentiates itself through its automation workflow builder (Workbench) and behavioral targeting — the ability to send follow-up messages based on keyword responses, contact field data, or inactivity triggers. It bundles SMS, email, and social messaging in one platform. Pricing starts at approximately $39/month on annual billing for the Lite tier, with Core plans at $94/month covering 3,000 SMS and 30,000 emails per month. Advanced plans start at $159/month with behavioral tracking and campaign consulting. Forbes named Trumpia the #1 SMS marketing provider in its coverage; G2 named it easiest to implement. The platform includes 50+ prebuilt workflow templates and 365-day phone support.
- • Workbench: Next-gen workflow builder with a free-form omnidirectional canvas for building complex, multi-branch customer journeys using drag-and-drop tile placement.
- • Smart targeting: Automatically segments contacts based on keyword responses, survey answers, or inactivity to route them into relevant follow-up sequences.
- • Review management: Collects and manages Google and Facebook reviews from within the Trumpia platform, without a separate review tool subscription.
- • Omnichannel messaging: SMS, email, and social media messaging managed from a unified inbox.
- • 50+ workflow templates: Prebuilt automation blueprints for common use cases including appointment reminders, cart recovery, employee communications, and event follow-up.
Trumpia is the right choice for mid-market teams that need sophisticated conditional automation and are willing to pay for a platform built around behavioral targeting and dedicated account support. Businesses with simpler campaign needs will overpay for features they won't use.
Avochato
Avochato is a San Francisco-based SMS and live chat platform founded in 2017, designed specifically for sales and support teams rather than mass marketing. Its three-component billing model includes a platform fee, a per-user fee, and a pay-as-you-go message balance. The Lite plan starts at $19/user/month for essential features. Standard tier is $35/user/month plus a $175/month platform fee. The platform supports SMS, MMS, WhatsApp (on higher tiers), voice calls, and web chat from a single shared inbox. Key integrations include Salesforce, Slack, Microsoft Teams, and Zapier. Unlike mass-texting platforms, Avochato is built for 1:1 and small-group conversations at scale.
- • Shared inbox: Multiple team members manage a single phone number's conversations, with assignment, escalation, flagging, and internal note threading.
- • Text tree routing: Incoming messages can be automatically routed to different team members or departments based on keywords or menu choices.
- • Salesforce integration: Bidirectional sync sends and logs SMS messages directly in Salesforce contact and lead records.
- • Voice calls: Avochato numbers handle both SMS and inbound/outbound voice calls from the same dedicated number — no separate VoIP subscription needed.
- • Account balance with budget caps: Set a maximum spend limit and receive low-balance alerts — message credits roll over and never expire.
Avochato earns its place for teams that specifically need SMS, voice, and webchat unified behind one number with a robust team inbox and Salesforce integration. The pricing cliff between Lite and Standard is the biggest adoption barrier — model the Standard tier cost carefully before committing.
Heymarket
Heymarket is a San Francisco-based business messaging platform founded in 2015 and SOC 2 Type 2 and HIPAA compliant. It supports SMS, MMS, Facebook Messenger, Instagram Messaging, WhatsApp, Apple Messages for Business, Google Business Messages, and web chat from a unified shared inbox. Pricing starts at $19/user/month (billed annually) for the Standard plan, $39/user/month for Plus, $59/user/month for Pro, with a 2-user minimum and a 14-day free trial. Each plan includes a set number of monthly message segments pooled across all inboxes — auto-upgrading to the next segment tier when the threshold is approached.
- • Multi-channel inbox: Manages SMS, WhatsApp, Apple Messages for Business, Facebook Messenger, Instagram, and web chat from a single shared inbox with consistent team workflow.
- • Mass Outreach: Bulk campaign sending with personalisation merge tokens, available on Pro plan and above, with shared segment pool billing.
- • AI agents: Auto-respond to customer questions and schedule appointments using AI trained on business-specific knowledge, available on Pro.
- • Salesforce and HubSpot integration: Bidirectional sync of message history into CRM contact records from both platforms.
- • HIPAA compliance: End-to-end message encryption and BAA availability makes Heymarket one of the few SMS platforms explicitly certified for healthcare use cases.
Heymarket is the top choice for healthcare, insurance, and financial services teams that need HIPAA compliance combined with a polished multi-channel inbox and CRM integration. Cost scales quickly with team size — evaluate the total monthly cost across your full user count before comparing to flat-rate alternatives.
Community
Community is a conversational SMS marketing platform founded in 2019, best known for powering celebrity and brand text-to-fan connections — clients include Paul McCartney, McDonald's, and Gary Vaynerchuk. The platform has facilitated over 3 billion texts between Leaders (brands/creators) and Members (subscribers), with claimed clickthrough rates of 59% and open rates of 95%. Community differs from broadcast SMS platforms by emphasising genuine two-way conversation at scale — subscribers can reply and receive personalised responses. Pricing is not publicly listed; Community requires a demo and quotes based on subscriber count and message volume.
- • Two-way engagement at scale: Members can reply to messages and receive personalised responses, creating conversation rather than one-directional broadcast.
- • Segmentation by interest and demographics: Segment member lists by self-reported interests, age, location, and engagement behaviour for targeted campaigns.
- • Multi-media messaging: Supports photos, videos, audio notes, GIFs, emojis, and links — covering the full range of modern smartphone messaging formats.
- • Creator-native UX: Platform UX is designed for individuals and brands managing personal relationships with fans, not for marketing operations teams.
- • Privacy focus: Community emphasises that member phone numbers are never shared with third parties and that opt-in is member-initiated.
Community is a compelling platform for artists, influencers, nonprofits, and culturally-relevant brands that want to build genuine relationships through SMS rather than broadcast marketing. It is not a fit for ecommerce conversion campaigns, transactional SMS, or teams that need transparent pricing before a sales conversation.
Hustle
Hustle is a peer-to-peer (P2P) SMS platform that enables organisations to conduct personalised 1:1 text conversations with large audiences using a distributed volunteer or staff team. Originally used primarily by progressive political campaigns, it has expanded to serve nonprofits, unions, and universities. Hustle's differentiator is Hustle Studio — a feature that lets organisations send video story-style clips as MMS messages, a capability not available on standard SMS marketing platforms. Pricing starts at $0.04 per SMS segment on the PAYGO plan (with a $100 setup fee), while the Annual Commitment plan starts at $10,000/year.
- • Peer-to-peer texting: Agents (volunteers or staff) use a mobile app to send scripted personalised messages and respond to replies individually — maintaining the human touch at scale.
- • Hustle Studio: Send video clips (approximately 30 seconds) as MMS messages directly embedded in text — no external links required.
- • Integrated dialer: Voice calling capability built into the Hustle workflow, allowing agents to switch from text to phone within the same contact session.
- • NGP VAN and Blackbaud integration: Native CRM integrations for political campaigns and nonprofits using the major sector-specific data platforms.
- • Workflows: Manage hundreds of simultaneous text conversations with pre-written scripts and AI-suggested responses to maintain consistent messaging across volunteer teams.
Hustle is worth the premium for well-funded political campaigns and large nonprofits that need video-capable P2P texting with NGPVAN integration. Smaller organisations with tighter budgets will find better ROI in Tatango for broadcast fundraising or CallHub for P2P at lower per-message rates.
Tatango
Tatango has operated since 2007 and has facilitated over $600 million in nonprofit fundraising through SMS. Its platform is exclusively focused on high-volume SMS for nonprofits and political campaigns. Tatango does not publish public pricing — all plans are tailored based on list size and messaging volume, with a Fast Start package designed to launch in as few as 20 days and a white-glove full launch in 60 days or less. The platform includes an entry package with 2,000 messaging credits/month (1 credit per SMS, 3 per MMS). Key integrations include Blackbaud Raiser's Edge, Salesforce, FundraiseUp, and EveryAction.
- • Nonprofit-native segmentation: AI-powered Power Segments identify the most likely donors based on giving history, engagement timing, and behavioral data.
- • Power Links: Personalised donation page URLs dynamically generated per subscriber, enabling prefilled gift amounts and donor recognition.
- • Tatango Inbox: One-to-one donor conversation management for major gift follow-up and donor service within the SMS platform.
- • White-glove launch: Tatango handles carrier approvals, short code provisioning, and compliance setup — clients do not manage their own carrier registration.
- • SOC 2 Type II and HIPAA compliance: Certified for healthcare nonprofits and health advocacy organisations handling protected data.
Tatango is the best SMS platform for US nonprofits ready to invest in a serious SMS fundraising program. The white-glove service model, Power Links, and 17-year fundraising specialisation justify the custom pricing for organisations where SMS drives 10%+ of digital revenue. Smaller nonprofits should evaluate Trumpia or SimpleTexting first.
Mobile Commons
Mobile Commons (now branded as mCommons, operated under Upland Software) is one of the oldest mobile advocacy platforms in the US, serving organisations including the Humane Society of the United States, SEIU, the Human Rights Campaign, and NYC MTA. It powers SMS, MMS, and emerging RCS campaigns with purpose-built tools for voter registration, legislative contact (connect-to-legislator calls), polling locators, and donation asks. Like Tatango, pricing is entirely custom and requires contacting mCommons for a quote. The platform integrates with ActBlue, GoFundMe Pro, Blackbaud, Salesforce, HubSpot, and Zapier.
- • Legislative calls: Built-in call-patching that connects SMS subscribers directly to their legislators with a single keyword reply — a feature absent from most commercial SMS platforms.
- • Polling locators: Delivers personalised polling location information to subscribers based on address — purpose-built for civic engagement campaigns.
- • Dynamic segmentation: AI-driven audience targeting based on engagement history, supporter tags, geographic data, and action completion status.
- • Peer-to-peer capabilities: Enables volunteer agent-based one-to-one texting alongside mass broadcast campaigns in the same platform.
- • Donation asks with mobile giving: Built-in donation links and text-to-give functionality without requiring third-party payment integration.
Mobile Commons is the most capable platform in the US for advocacy, political, and civic SMS programs that need legislative action tools, peer-to-peer, and broadcast in one system. For nonprofits whose primary need is fundraising rather than legislative engagement, Tatango is a more focused alternative.
Vibes
Vibes is a Chicago-based mobile engagement platform founded in 1998, operating for 25+ years and recognised as one of only four Tier 1 CSCA aggregators in North America. It powers SMS, MMS, RCS, push notifications, and Apple Wallet / Google Pay marketing for enterprise brands including Chipotle, Polo Ralph Lauren, Kohl's, and Hibbett. Vibes processed over 60 billion messages in 2025. Its AI-powered Nexus engine provides send time optimisation, audience segmentation recommendations, and copy suggestions. Pricing is not publicly listed and requires a demo. RCS launch capabilities are a major 2025–2026 focus, with Vibes claiming 30% revenue uplift versus SMS for early RCS adopters.
- • Tier 1 aggregator status: One of only four companies with direct CSCA-recognised carrier connections across all major US networks — eliminating aggregation latency for enterprise volumes.
- • Mobile Wallet marketing: Delivers digital coupons, loyalty cards, and event tickets directly to Apple Wallet and Google Pay with real-time update capability.
- • RCS deployment: Vibes is the leading RCS agent deployment partner for US brands in 2025, with early adopters reporting 3x higher engagement versus SMS.
- • Nexus AI engine: Machine learning send time optimisation, audience segmentation, and copy recommendations built into the platform dashboard.
- • Integrations: Salesforce Marketing Cloud, Adobe Marketo Engage, Adobe Journey Optimizer, Oracle CrowdTwist, Narvar, Snowflake, and others.
Vibes is the right platform for Fortune 1000 retail and restaurant brands running mature, high-volume mobile loyalty programs where Mobile Wallet and RCS are strategic channels alongside SMS. There is no meaningful self-serve or mid-market option — if your brand is not already sending millions of messages per month, evaluate Attentive or Klaviyo first.
Brevo SMS
Brevo (formerly Sendinblue) is a Paris-based marketing platform serving over 500,000 businesses globally with email, SMS, WhatsApp, live chat, CRM, and transactional messaging in one tool. SMS is available as a prepaid credit add-on on all plans — credits are purchased in packs of 100 minimum, never expire, and are priced per destination country. In the US, 1,000 SMS credits cost approximately $31.59. Unlike SMS-specialist platforms, Brevo's SMS capability is a channel within a broader marketing platform — it works through the same campaign builder as email. Brevo's email plans start at $0 (free forever, 300 emails/day), Starter at $9/month, Standard at $18/month, and Professional at $499/month.
- • Unified multi-channel campaigns: Build automation journeys that span email, SMS, WhatsApp, push notifications, and live chat from a single campaign workflow editor.
- • Prepaid SMS credits: No SMS subscription required — purchase country-specific credit packs that never expire and are used across any plan tier.
- • Marketing automation: Trigger-based workflows for welcome series, cart abandonment, purchase confirmation, and re-engagement sequences.
- • CRM features: Contact management, deal pipelines, and task tracking built into the platform — reducing the need for a separate CRM for SMBs.
- • 150+ integrations: Shopify, WooCommerce, Magento, WordPress, Salesforce, and 150+ other platforms via native connectors.
Brevo SMS makes sense for businesses already using Brevo for email that want occasional SMS capability without adding a second platform. As a primary SMS marketing tool, it is more expensive per message than dedicated SMS platforms. The free email plan is a legitimate competitive advantage for startups evaluating their first multi-channel marketing stack.
Omnisend SMS
Omnisend is a Copenhagen-based ecommerce marketing automation platform serving over 125,000 online stores, with Shopify, WooCommerce, and BigCommerce as its primary integrations. It competes directly with Klaviyo, positioning itself as more affordable and feature-accessible at comparable list sizes. All plans — including the Free tier — include full access to automation, segmentation, A/B testing, and reporting. SMS is billed separately as a credit subscription: US SMS costs $0.015 per message (compared to Klaviyo's ~$0.01). The Free plan supports 250 contacts with 500 emails/month and 60 free SMS credits. Standard starts at $16/month; Pro at $59/month includes monthly SMS credits equal to the plan cost.
- • All features on all plans: Every automation template, A/B test, form type, segmentation option, and reporting feature is accessible from the Free plan — no feature gating.
- • Pro SMS credits: On the Pro plan, monthly SMS credits equal your plan cost (e.g., $59/month plan = $59 in SMS credits/month) — effectively bundling SMS into the plan price.
- • Ecommerce automations: Pre-built workflows for cart abandonment, welcome series, post-purchase, and product review requests with native ecommerce data triggers.
- • Web push notifications: Available on Standard and Pro plans; managed from the same campaign builder as email and SMS.
- • Product Reviews: Native review collection and display capability available on Shopify stores.
Omnisend is the strongest Klaviyo alternative for growing ecommerce brands that prioritise feature accessibility over deep Shopify-native tooling. At list sizes above 10,000 contacts, it consistently prices out more affordably than Klaviyo while offering comparable automation capabilities. The SMS-bundled Pro plan is good value for brands sending 3,000+ US texts per month.
Sendlane
Sendlane is a San Diego-based email and SMS marketing platform founded by Jimmy Kim, targeted at mid-market DTC brands generating between $1M–$50M in annual revenue. Unlike Klaviyo, Sendlane charges based on emails sent rather than contact count — a meaningful advantage for brands with large databases that communicate infrequently. SMS plans start at $50/month for 2,500 credits (1 credit = 1 SMS; 3 credits = 1 MMS). SMS pricing starts at $0.009 per credit including carrier fees, which is competitive at volume. A 60-day free trial (500 emails, no credit card) is available. Sendlane is built on its own sending infrastructure rather than reselling SendGrid, which the company claims improves deliverability.
- • Send-based pricing: Charges per email sent rather than per contact stored — brands with 200,000 contacts who send once a month pay for 200,000 sends, not 200,000 contacts.
- • Own sending infrastructure: Sendlane operates its own email delivery infrastructure (not SendGrid/Mailgun), which the company attributes to above-average inbox placement rates.
- • 24/7/365 support: Live chat and email support on all plans with average 30-second response times — not limited to business hours or higher tiers.
- • Ecommerce automations: Pre-built flows for cart abandonment, post-purchase upsell, welcome series, and win-back campaigns with Shopify and WooCommerce triggers.
- • Direct Rate SMS: For brands spending $1k+/month on email, Sendlane offers SMS at carrier cost ('you pay what we pay') for a limited promotional period.
Sendlane is a compelling alternative to Klaviyo for mid-market DTC brands with large, infrequently emailed databases — the send-volume pricing model can result in meaningful monthly savings. The US-only SMS restriction is a real limitation for internationally-shipping brands. Verify SMS pricing specifics in writing before signing an annual contract.
