Top 5 Shopify SMS Marketing Apps

SMS marketing delivers what email can't: near-instant open rates (98% vs email's ~20%) and a direct line to your customer's pocket.

For Shopify merchants, the right SMS app turns abandoned carts into completed orders and one-time buyers into repeat customers.

But the landscape has consolidated. What was once a fragmented market of standalone SMS tools is now dominated by platforms that combine email, SMS, and increasingly, AI-powered automation. 

Pricing models vary wildly; some charge per contact, others per message, and a few bundle SMS credits into email plans.

We evaluated the top SMS marketing apps available for Shopify stores based on features, pricing transparency, Shopify integration depth, and user feedback from app store reviews.

What to Look for in an SMS Marketing App

Before diving into the list, here's what matters the most:

• Compliance built in: SMS marketing has strict regulations (TCPA in the US, GDPR in Europe). Your app should handle opt-in/opt-out automatically.
• Automation capabilities: Abandoned cart flows, welcome series, and post-purchase follow-ups should work out of the box.
• Segmentation: The ability to target messages based on purchase history, browsing behavior, and customer lifetime value.
• Two-way messaging: Conversational SMS can drive higher engagement than one-way blasts.
• Pricing clarity: Some apps advertise low starting prices but charge per message on top. Understand the true cost at your volume.

Use this list as a guideline for your decision. If you want a head start, check out our recommendations below.

The Best SMS Marketing Apps for Shopify Stores

1. Klaviyo

What it is: Klaviyo is a combined email and SMS marketing platform that has become the default choice for Shopify stores. It syncs Shopify data in real-time, enabling highly personalized automated flows across both channels.

Platform: Shopify, Shopify Plus, WooCommerce, BigCommerce, and 350+ integrations

Pricing:

• Free: Up to 250 contacts, 500 emails/month, 150 SMS credits
• Email only: Starting at $20/month for 251-500 contacts
• Email + SMS: Starting at $35/month for 251-500 contacts
• SMS credits: 1 credit per US text, 3-15 credits for MMS depending on region

Key features:

• Real-time Shopify data sync (orders, browsing, customer data)
• Pre-built automation flows for abandoned cart, welcome series, post-purchase
• Advanced segmentation using purchase and browsing behavior
• AI-generated subject lines and message copy

How it works: Klaviyo pulls your Shopify data automatically and lets you build flows that trigger SMS messages based on specific customer actions—like abandoning a cart or viewing a product multiple times without purchasing. You can combine SMS with email in the same automation.

What users say: "Klaviyo is hands-down one of the most powerful email and SMS platforms out there for ecommerce. The depth of analytics is a key strength, providing data that helps make smarter decisions." The main criticism: pricing based on all contacts in your account, not just those you message.

Quick Comparison

Which App Should You Choose?

There's no single "best" SMS app. The right choice depends on your current stack and priorities.

If you're already using Klaviyo for email: Adding SMS through Klaviyo makes sense. You keep everything in one platform with unified customer profiles and reporting.

If you want SMS-specific optimization: Postscript's SMS-first approach and AI testing tools are designed for brands that see SMS as a primary channel, not an add-on.

If you want hands-on support: Recart's dedicated Customer Success Manager model means you're not figuring things out alone. Higher starting price, but includes strategic guidance.

If you want the simplest pricing: Omnisend's bundled SMS credits eliminate the complexity of per-message billing. You know your monthly cost upfront.

If you're a larger brand with custom needs: Attentive's enterprise features and Text-to-Buy integration may justify the higher cost and sales process.

Getting Started

Most of these apps offer free tiers or trials. The best approach:

1. Start with one app that fits your current email/marketing stack
2. Set up core automations first: abandoned cart, welcome series, post-purchase
3. Build your subscriber list with compliant opt-in forms
4. Measure ROI before scaling up to higher tiers or message volumes

SMS marketing works. The question is which platform fits your workflow and budget.
