10 Best SMS Marketing Software of 2026

SimpleTexting covers what most small businesses need from text marketing and keeps the setup short. The entry plan costs $29 per month for 500 credits, and paying yearly cuts the price by 20%. Every paid plan includes mass texting, two-way conversations with free incoming replies, auto-replies, drip campaigns, MMS, unlimited contacts and keywords, opt-in forms, segments and three user seats, so there is no feature gate to plan around. Unused credits roll over, which helps seasonal senders. SimpleTexting can text-enable an existing landline or toll-free number, and support runs seven days a week by phone, text, chat and email. The costs to watch are add-ons: a local number is $10 per month plus a $4 activation fee, each extra teammate is $20 per month, and carrier fees average about $0.0025 per US message on top. Shops that need deep ecommerce flows tied to store data will get more from Postscript or Klaviyo.

EZ Texting has the cheapest verified way into a full texting platform on this list. Launch costs $20 per month billed annually or $25 monthly and includes 500 credits a month, unlimited contacts, keywords, QR codes, signup forms and click-to-text buttons. All plans share the same core tools: AI Reply and AI Compose, a Shutterstock media library, a scheduling calendar, drip campaigns, a team inbox, call forwarding, branded contact cards and text-to-pay or text-to-donate links, plus an open API. Higher tiers mainly change the number you send from. Boost at $60 per month billed annually moves you to a high-volume local number and waives the $5 telecom fee, and Scale at $100 adds a faster number and an onboarding specialist. The catch on Launch is one included user and $0.04 overage credits, so a team that texts often will move up quickly. EZ Texting also supports Canada and offers RCS messaging.

SlickText prices purely on message volume and keeps every feature on every plan, which makes it easy to budget. The entry plan is $29 per month for 500 credits, and the ladder runs through $49 for 1,000, $79 for 2,000 and up to $939 for 50,000 credits. Each tier includes campaigns, a one-on-one inbox, multi-branch workflows, web forms, popups, dynamic segments, analytics and integrations, along with free incoming texts, unlimited contacts and rollover credits. Live phone, chat and email support is available from the first plan, which is rare at this price. Annual billing adds two months of credits for free and lets you spend them unevenly across the year. The limits are geographic and service related. SlickText sends only to the US and Canada, 1-on-1 onboarding starts at the $129 plan, a dedicated success manager starts at $579, and RCS carries separate setup and annual fees.

Klaviyo makes the most sense when texts are one part of a wider ecommerce program. SMS sits on the same customer profile as email, so segments, flows and reporting cover both, and multi-channel flows can pick the right channel for each shopper. The SMS tools include automated keyword conversations, an AI Customer Agent that answers questions and recommends products, separate marketing and transactional consent, a Compliance Hub, location-based messages and Shopify POS data that links in-store purchases back to campaigns. The free plan covers 250 active profiles, 500 emails and $5 of mobile messages a month, which is enough to test texting. Paid pricing depends on profile count and message volume, and we could not confirm a USD starting price at our check, so it is marked pending. The trade-off is complexity: teams that only want to send texts will set up SimpleTexting or SlickText faster.

Postscript is the most store-focused SMS tool here, and its pricing reflects that. Starter has no subscription fee but a $49 monthly minimum spend, with SMS at $0.009 and MMS at $0.045 plus carrier fees. Growth at $100 per month lowers the message rate, unlocks unlimited opt-in keywords and adds live chat support, and Professional at $500 per month adds enhanced analytics, API access and removes the Postscript badge from opt-ins. Every plan includes a visual flow builder with cart and browse abandonment, welcome, upsell and shipping templates, popups and checkout collection, Shopify-based segmentation, response management and a dedicated toll-free number. Postscript now also sends RCS and email, and its AI Plan at $699 per month adds Infinity Testing and Shopper journeys. The fit is narrow on purpose. Brands outside Shopify, or businesses that mainly send reminders and local offers, will find SimpleTexting or EZ Texting easier.

Textedly keeps pricing simple: one feature set, many volume tiers. Basic costs $29 per month for 500 messages, Bronze $49 for 1,000 and Elite $169 for 5,000, and paying annually adds 20% more texts each month instead of a discount. Every account gets text-to-pay requests through Stripe, Google review requests, MMS, contact enrichment and conversational AI voice and SMS agents, and messages can run to 1,600 characters. Each account includes a free toll-free number and a free 10DLC number, and Textedly pays the carrier registration for the first local number. Teammates are unlimited at $10 per month each. A free account starts you with 50 messages and one keyword with no time limit, which is a fair way to test the interface. The published material says less about workflow depth and segmentation than SlickText or SimpleTexting, so stores that run complex journeys may want to trial both.

Omnisend suits stores that want email and texting in one tool without enterprise pricing. SMS and MMS sit on the Pro plan, which the pricing page lists at $177 for the first three months at 2,500 contacts, about $59 a month, shown as $41.30 a month during a 30% introductory discount. Pro adds unlimited monthly emails, advanced reporting, AI agents for forms, dynamic content and product recommendations, and bonus SMS credits equal to your monthly bill. US message rates start at $0.009 and drop to $0.007 for spend of $10,000 or more, and MMS is limited to the US and Canada. Support runs 24/7 by live chat and email on every plan, and Omnisend migrates lists, segments and flows for free. The drawback for an SMS list is that the Free and Standard plans do not send texts, so Pro is the real starting point, and its price climbs with your contact count.

Sakari is the pick here for teams that text from a CRM or across borders. Plans start at $25 per month and include one free dedicated number in the US, Canada, the UK or France, or an alphanumeric sender ID, and add-on numbers in more than 20 countries start at $4 per month. On the entry plan a US message costs $0.0304 per segment, and MMS adds $0.02. All plans include unlimited users and contacts, rollover credits that last 90 days, mass texting, two-way messaging, auto-replies, drip campaigns, opt-in forms, a URL shortener, API access and native integrations with HubSpot, ActiveCampaign, Pipedrive and Slack. That mix fits sales and service teams more than retail marketers. Sakari lacks the popups, store-driven flows and payment links that Postscript, Klaviyo or EZ Texting offer, so ecommerce brands will find more in those tools.

Attentive is built for big retail programs, and its sales model shows it. There is no public price list: plans are assembled with the sales team based on message volume, subscriber list size, channels and premium AI tools. Every plan includes strategic planning, onboarding and deliverability help, a dedicated support team with 24/5 service, 150+ pre-built integrations, the Attentive Signal identity tag, patented two-tap sign-up units, pre-built cross-channel journeys, A/B testing, campaign and segment reporting and built-in TCPA compliance tools. Beyond SMS, the platform sends email, RCS and push, and reaches subscribers in more than 20 countries. That depth and service is why large brands use it, but it also places Attentive out of reach for most small businesses, and the lack of published pricing makes direct comparison hard. Mid-size stores will usually get similar ecommerce flows from Postscript or Klaviyo at a known price.

Textmagic works on prepaid credit rather than a monthly plan, which suits businesses whose sending swings from month to month. The account covers mass texting, automation workflows triggered by forms, replies and appointments, a shared team inbox, an omnichannel chat widget and email campaigns, with unlimited contacts and users. Compliance help is a strong point: Textmagic guides US 10DLC and toll-free registration with AI checks before submission, handles STOP and HELP replies, and helps with consent capture for the UK and Canada. It also connects to AI assistants through MCP alongside a standard API and integrations. We could not confirm which country the default rates on the pricing page referred to when fetched from our location, so the USD price is marked pending. Marketers who want popups, store-triggered flows or payment links will find more in SlickText, EZ Texting or Postscript.
