6 Best Shopify SMS Marketing Apps in 2026

Our general guide to SMS marketing platforms covers how to choose a texting tool and where SMS fits in a wider stack. This roundup is narrower: apps a Shopify merchant can install from the Shopify App Store, judged on what matters to a store, such as order and cart data, opt-in tools, and what you pay per message as the list grows.

What to look for in a Shopify SMS app

• Store data in every message. Abandoned cart, browse and order events should trigger flows without custom code.
• List growth tools. Popups and keyword opt-ins that collect consent properly, because the list is the asset.
• Clear per-message pricing. SMS costs scale with every send, so the per-text rate matters more than the plan fee.
• Compliance handled. Opt-in records, STOP and HELP keywords, quiet hours and registered sending numbers.
• Email in the same place, or not. Decide whether you want one tool for email and SMS or a specialist for each.

How we picked these apps

Each app had to be installable from the Shopify App Store in October 2026, send SMS marketing campaigns and automated flows, and show its pricing on its App Store listing or help center. We read every price on those pages in October 2026. Star ratings and review counts change daily, so we have left them out. One well-known option, Yotpo's email and SMS app, was listed as not currently available on the Shopify App Store when we checked, so it is not included.

At-a-glance comparison

The best Shopify SMS marketing apps

1. Shopify Messaging: SMS without another app

Shopify Messaging, formerly Shopify Email, sends email, SMS and WhatsApp campaigns from the Shopify admin to customers who opted in. Merchants on Basic, Grow, Advanced and Shopify Plus plans can use it, and charges appear on the Shopify bill as Messaging.

Pricing (as of October 2026): free to install; SMS is charged per message by country, $0.012 per message to the United States, and each approved toll-free number used for SMS marketing in the US and Canada costs $2.15 a month. Confirmation, double opt-in and keyword replies are also charged per message, and up to 25 test messages a week are free. Strengths: nothing extra to set up or learn. Limits: built for straightforward campaigns, so check that its automations cover the flows you need before you rely on it.

2. Klaviyo: email and SMS on one profile

Klaviyo's Shopify app covers email, SMS and WhatsApp, with multi-channel segmentation, smart opt-in, SMS AI and automated conversations. Store data flows into each profile, so the same segments and cart or order events can drive both email and SMS. It also offers RCS in supported countries; see our RCS business messaging comparison.

Pricing (as of October 2026): the App Store listing shows a free plan, an SMS plan at $15 a month for up to 1,250 SMS/MMS credits and an Email plan from $20 a month for 251 to 500 contacts, billed every 30 days in USD. Strengths: one tool for both channels, with shared segments. Limits: cost rises with both contacts and credits as the store grows.

3. Postscript: the SMS specialist with published rates

Postscript is built only for text marketing on Shopify: campaigns, automation flows, abandoned cart recovery, segmentation and compliance tools.

Pricing (as of October 2026): Starter is free to install with a $49 monthly minimum spend, then $0.009 per SMS and $0.045 per MMS plus carrier fees. Growth costs $100 a month ($0.008 per SMS, $0.03 per MMS) and Professional $500 a month ($0.007 per SMS, $0.024 per MMS). Every plan starts with a $100 credit for the first 30 days, and Growth and Professional include a 30-day free trial. Strengths: transparent per-message pricing that falls as you scale. Limits: SMS only, so email lives in another tool.

4. Omnisend: email first, SMS when you need it

Omnisend combines email, SMS, popups and web push for ecommerce. Its free plan covers 250 contacts and 500 emails a month, and its pricing page lists SMS on every plan, paid for with credits.

Pricing (as of October 2026): Standard is $16 a month for up to 500 contacts and 6,000 emails; Pro is $59 a month for up to 2,500 contacts with unlimited emails. Both were listed with 30% off the first three months. US SMS costs $0.009 per message at the smallest credit volume, falling to $0.007 at the highest volume tier. Strengths: a low per-message SMS rate inside an affordable email tool. Limits: the lowest SMS rate needs high volume.

5. Attentive: for brands where text is a major channel

Attentive runs SMS and email for larger brands, with AI-led campaigns and journeys, and adds RCS for richer messages in the same platform.

Pricing (as of October 2026): free to install, with additional charges billed by Attentive separately from your Shopify invoice; the listing offers a minimum 30-day free trial, then month-to-month or longer agreements. Strengths: scale and support for big subscriber lists. Limits: no public price list, which makes it hard for a smaller store to budget.

6. Recart: SMS with a managed service

Recart pairs its SMS app with a fully managed service and AI text campaigns, plus email and SMS list growth popups, automation flows and compliance features.

Pricing (as of October 2026): a free plan for migration and onboarding with no platform fee, and a Starter plan at $299 a month with a 7-day free trial, advanced segmentation and international texting. Strengths: hands-on help for stores without an SMS marketer. Limits: the paid plan is a large step up from the free tier.

Which one fits your store?

If you send a campaign a month to a few thousand subscribers, Shopify Messaging keeps things simple. Once flows such as abandoned cart and post-purchase carry real revenue, move to Klaviyo or Omnisend if you want email in the same tool, or Postscript if SMS deserves its own specialist. Brands with large lists and a team to run them should talk to Attentive or Recart. Whatever you choose, test the per-message cost against your real send volume before you commit. If many of your customers are outside the US, our roundup of WhatsApp marketing platforms covers that channel, and our ecommerce email tool comparison covers the email side.
