9 Best SMS Marketing Software of 2026

Postscript is the most store-focused texting tool on this list. Every plan includes a visual flow builder with templates for cart and browse abandonment, welcome series, upsells and shipping updates, plus popups, checkout collection and its Onsite Opt-in for list growth. Segments use Shopify data and third party integrations, and you can answer customer replies from the same account. Pricing is usage-based: 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 a month cuts the SMS rate to $0.008 and unlocks unlimited keywords and live chat support, while Professional at $500 adds API access and enhanced analytics. A dedicated toll-free number is included and verified for free, and a short code costs the carriers' $750 a month at no markup. The main limit is the Shopify focus: brands on other platforms must add Postscript's SDK to their store code.

Klaviyo treats SMS as one channel inside a wider customer platform, which is its main strength for stores that already email. Texts run in the same flows, segments and reports as email, and last-touch multi-channel attribution avoids counting one sale twice. Klaviyo documents SMS in more than 20 countries, separate consent for marketing and transactional texts, a Compliance Hub, age gating for alcohol brands and Location Hub reporting that ties Shopify POS purchases back to campaigns. Over 70 sign-up form templates help build the list. The free plan covers 250 active profiles and includes $5 of mobile messages a month, and the SMS calculator on Klaviyo's product page shows $15 a month for 1,000 US toll-free messages. On the paid Email and Marketing plans, SMS is an add-on, and message credits differ by recipient country. Brands that only want texting will pay for email tools they may not use.

Omnisend combines email, SMS and web push for online stores and keeps the entry price lower than the larger ecommerce platforms. SMS and MMS sit on the Pro plan, which the pricing page shows at $41.30 a month when you pay 3 months upfront for a 30% saving. Pro also includes unlimited monthly emails, unlimited web push, advanced reporting that compares email and SMS results, and bonus SMS credits equal to your monthly bill, so part of the subscription comes back as texts. Omnisend says SMS rates start at $0.007 per message, though that rate applies to high-volume US sends and prices vary by country. Support is a strong point: 24/7 live chat and email support covers every plan, including Free. Migration is free and takes about 5 days. The trade-off is that you cannot text on Free or Standard, so stores that only want SMS must still buy the Pro bundle.

SimpleTexting is a general business texting service that works well for shops, restaurants and franchises that want to send offers without wiring up store data. Every plan includes mass texting, two-way messaging, auto-replies, drip campaigns, MMS, an AI message generator, API access, unlimited contacts, unlimited text-to-join keywords, opt-in forms and pop-ups. The entry plan costs $29 a month for 500 credits with extra credits at 5.5 cents, and a local number adds $10 a month plus a $4 activation fee. Annual billing saves 20% and gives seasonal businesses their credits upfront. Monthly plans roll unused credits over to the next month, incoming SMS is free, and nonprofits get 15% off. Three users are included, with extra seats at $20 a month. Integrations cover Mailchimp and Zapier rather than direct ecommerce connections, so cart and order texts need extra setup. SimpleTexting says it has more than 17,000 paying customers.

EZ Texting has the lowest entry price among the monthly texting services here: Launch costs $25 a month or $20 a month billed annually and includes 500 credits and a local textable number. Every plan includes unlimited contacts, keywords, QR codes and signup forms, AI Compose and AI Reply, a Shutterstock media library, a scheduling calendar, drip campaigns, keyword auto-replies, text-to-pay links, a team inbox and an open API. Workflows automate after-hours replies, reminders and abandoned cart recovery, which helps small online sellers without an ecommerce texting tool. EZ Texting also offers RCS messages with a verified business name and logo. The limits show up as volume grows: Launch includes 1 user, overage credits cost $0.04 each, and the telecom fee is only waived from Boost at $75 a month. An MMS uses 3 credits, so picture-heavy promotions burn through the plan quickly. Set-up takes about 1 business day.

SlickText keeps pricing simple: plans differ only by monthly credits, and every plan includes integrations, Workflows and the full feature set. The entry plan costs $29 a month for 500 credits, then $49 for 1,000 and $79 for 2,000, with 1 SMS using 1 credit and 1 MMS using 3. Each paid tier lists unlimited contacts, free incoming texts, rollover credits, live phone, chat and email support, one premium sending number, 1 on 1 onboarding and a dedicated customer success manager. Paying yearly gives 2 months of credits free and lets you spend a year of credits unevenly, which suits retailers with holiday peaks. SlickText now offers RCS messages with a verified business profile, but that costs a $500 one-time setup fee and a $200 annual fee. Messaging is limited to the United States and Canada, so brands with customers abroad need another tool. Eligible nonprofits get 20% off.

Textedly sells one feature set on every plan and changes only message volume and keyword limits as you move up. Basic costs $29 a month for 500 messages, Bronze $49 for 1,000 and Plus $79 for 2,000, and annual billing adds 20% more messages per month. Every account includes custom keywords, picture messaging, Text-to-Pay, Google Business Reviews, a Contact Enrichment suite and conversational AI voice and SMS agents. Each account also gets a free toll-free number and a free 10DLC number, and Textedly pays the 10DLC registration cost for your first local number, which removes one of the common setup fees. You can start with a free account that includes 50 texts and one keyword with no credit card and no time limit. Teammates are unlimited but cost $10 a month each. There are no long-term contracts, and incoming messages are free. Ecommerce connections run through its 3,000+ integrations rather than native store flows.

Attentive is built for large consumer brands that want a full-service texting program. 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, the patented two-tap sign-up, pre-built cross-channel journeys, A/B testing frameworks, campaign and segment reporting and built-in TCPA compliance tools. Channels cover SMS, MMS, RCS, email and push, and AI add-ons such as AI Pro and AI Grow are sold for a flat monthly fee. Attentive does not publish prices: you get a modular plan after a demo, priced on messages sent, list size, channels and AI tools. That process and the level of service suit brands with large lists and a marketing team, but it is more than a small store needs, and you cannot sign up and start texting the same day. We scored value conservatively because no price is published.

Textmagic suits businesses that text in bursts rather than every week. There is no subscription: outbound SMS costs $0.049 per 160-character message, MMS costs $0.08, and inbound SMS is free. A local or toll-free number costs $10 a month after a free first month. If you already have a Twilio, Vonage, Sinch or Bandwidth account, Textmagic can send through it for $0.01 per SMS. Compliance help is a strength: guided 10DLC and toll-free registration with AI checks, automatic STOP and HELP handling, TCPA-ready consent forms and setups for the UK, Canada, Australia and Europe. The platform also handles email campaigns, with the first 10,000 emails free, and a shared inbox for SMS, live chat and social channels. It is less suited to ecommerce brands, since it lacks native store flows like cart recovery, and at steady volume the per-message price costs more than a bundled plan.
