Why SMS Marketing Apps Matter for Shopify Stores

Shopify does support basic SMS messaging, but its built in features are mainly used for transactional notifications, such as order and shipping updates. They are not designed for running SMS marketing campaigns, grouping customers, or managing consent at scale. Because of this, many merchants choose a dedicated Shopify app for SMS marketing.

SMS has also become an important marketing channel worldwide. Global SMS advertising spend is expected to reach $809.05 million in 2025, with the United States contributing about $318.5 million, based on data from Statista and cited by Omnisend. This shows that more brands are using SMS to reach customers at high-intent moments on mobile.

SMS marketing apps help fill this gap. They give Shopify merchants better control over automation, opt-in rules, and message timing. In simple terms, Shopify’s native SMS helps you send updates, while a Shopify app for SMS marketing helps you drive sales and retention in a more structured way.

How We Chose the Best SMS Marketing Apps for Shopify

This guide is not based on which app has the most features. Instead, we focused on how well each SMS marketing app supports real Shopify store needs in different situations. Not every store uses SMS the same way, and no single app is the best fit for everyone.

We evaluated each app using the following criteria:

• Shopify integration quality: How reliably the app connects with Shopify data, such as customers, orders, and checkout events.
• Automation and workflow support: Whether the app can run common SMS workflows like abandoned cart reminders and post-purchase messages without manual effort.
• Conversation handling: How the app manages customer replies, including two-way messaging and conversation visibility.
• Consent and compliance controls: How clearly the app handles opt-in, opt-out, quiet hours, and compliance requirements.
• Pricing clarity and growth fit: Whether pricing is transparent and how well the app scales as SMS volume increases.

We also looked at store size and use case fit. Some SMS apps are designed for beginners, others for high-volume brands, and some for specific purposes such as conversational cart recovery. Because of this, an app does not need to perform equally well in every category to be a strong choice for the right store.

1. Omnisend Email Marketing & SMS

Price: Free to install with limited usage. Paid plans start at $16/month, with higher tiers such as $59/month as usage increases. SMS messages are billed separately based on volume.

Best for: Shopify stores that want to run SMS and email marketing together from one platform.

Omnisend is a multi-channel marketing app used by over 100,000 Shopify brands that combines SMS, email, and push notifications in a single dashboard. It is commonly chosen by stores that already rely on email marketing and want to add SMS without switching to a separate, SMS only tool.

Key features:

• Unified SMS and email automation, allowing merchants to manage campaigns from a single interface
• Pre-built Shopify workflows, including abandoned cart and post-purchase messages that can be enabled with minimal setup
• Native Shopify integration, with access to checkout, customer, and order data
• Performance tracking and reporting, showing revenue attribution across channels

Limitations:

• SMS functionality is less advanced than SMS only platforms, especially for conversational or high volume messaging
• SMS costs scale with usage, which can increase total spend as message volume grow

When this app is a good fit (and when it’s not): 

Omnisend is a good fit for Shopify stores that want a straightforward way to add SMS to an existing email marketing setup and prefer ease of use over deep SMS customization. If your store depends heavily on SMS as a primary revenue channel or requires advanced two-way messaging, a dedicated SMS marketing app may be a better choice.

2. Klaviyo: Email Marketing & SMS

Price: Free to install. SMS plans start at $15/month, which includes up to 1,250 SMS credits with carrier fees included. Email plans start at $20/month, and pricing scales with usage.

Best suited for: Shopify brands that heavily rely on customer data and segmentation to inform marketing decisions.

Klaviyo is a data-driven marketing platform that combines SMS and email with deep Shopify integration.  It is widely used by growing and established Shopify brands that want to trigger messages based on real customer behavior, purchase history, and on-site activity rather than relying on basic workflows.

Compared to Omnisend, Klaviyo places more emphasis on data depth and segmentation rather than ease of setup and multi-channel simplicity.

Key features:

• Deep Shopify data integration, with access to customer events, order history, and on-site behavior
• Advanced segmentation and targeting, allowing highly personalized SMS campaigns
• Automated SMS and email flows, including abandoned cart and post-purchase messages
• Performance reporting and attribution, helping track how SMS contributes to revenue

Limitations:

• Setup and daily use can feel complex for smaller or non-technical teams
• Costs increase quickly as contact lists and SMS volume grow

When this app is a good fit (and when it’s not): 

Klaviyo SMS is a good fit for Shopify brands that already use customer data actively and want fine-grained control over segmentation and automation. For small stores just starting with SMS or teams looking for a simpler setup, Klaviyo may feel more complex and costly than necessary.

3. TxtCart

Price: Free to install. Paid plans start at $79/month, with higher tiers such as $199/month and $499/month depending on usage and features. SMS usage and recovery volume affect total cost.

Best for: Shopify stores that want to focus on conversational abandoned cart recovery rather than full lifecycle SMS marketing.

TxtCart is an SMS marketing app built specifically around two-way, conversational messaging for cart recovery. Instead of relying on fully automated flows, it uses AI-assisted conversations to follow up on abandoned carts and checkouts in a more human-like way.

Compared to Klaviyo SMS, which emphasizes data-driven automation across the customer lifecycle, TxtCart focuses on direct conversations aimed at recovering high-intent abandoned carts.

Key features:

• Two-way SMS conversations, allowing customers to reply and engage in real time
• AI-assisted cart recovery, designed to follow up on abandoned carts and checkouts automatically
• Built in SMS compliance and analytics, helping stores track recovery performance
• One click Shopify data syncing, making setup relatively fast for cart focused use cases

Limitations:

• Not designed for full lifecycle SMS campaigns such as long term retention or promotional broadcasts
• Higher starting price compared to general purpose SMS tools, especially for small stores

When this app is a good fit (and when it’s not):

TxtCart is a good fit for Shopify stores that generate enough abandoned carts to justify a conversational recovery approach and want to maximize recovery rate rather than manage broad SMS campaigns. For stores looking for a more traditional SMS marketing platform with flexible automation and lower entry cost, a general purpose SMS app may be a better fit.

4. ONE AI, Pop Up, SMS Marketing

Price: Free plan available for test and sandbox stores. Paid plans start at $9/month, with pricing increasing based on usage and enabled features.

Best for: Shopify stores looking for an all-in-one marketing tool that combines SMS, email, pop-ups, and basic automation in a single app.

ONE is a multi-purpose marketing app designed to replace several Shopify marketing tools with a single platform. It combines SMS, email, pop-ups, upsells, and basic automation, with a strong focus on simplicity and broad feature coverage rather than deep specialization in one channel.

Compared to TxtCart, which focuses narrowly on conversational cart recovery, ONE takes a broader but less specialized approach, aiming to cover multiple marketing needs at a lower entry cost.

Key features:

• All-in-one marketing toolkit, including SMS, email, pop-ups, upsells, and discounts
• AI-powered automation, such as basic chat and content assistance
• Shopify checkout and customer integration, enabling abandoned cart and recovery flows
• A B testing and coupon tools, supporting basic optimization across campaigns

Limitations:

• Individual features are less advanced than dedicated tools, especially for SMS only strategies
• Mixed reviews around pricing changes and feature depth suggest it may not suit complex setups

When this app is a good fit (and when it’s not):

ONE is a good fit for Shopify stores that want to keep their marketing stack simple and prefer one app that covers multiple use cases at a low starting cost. For stores that need advanced SMS automation, deep segmentation, or a best in class solution for a specific channel, a more specialized SMS marketing app may be a better choice.

5. Attentive

Price: Free to install, with additional charges billed separately by Attentive. Pricing is custom and usage-based, typically requiring a minimum commitment after the free trial.

Best for: Mid- to large Shopify brands that require enterprise-level SMS and email marketing, with strong compliance and personalization support.

Attentive is an AI-powered SMS and email marketing platform built for brands that operate at scale and require advanced personalization and compliance controls. It focuses on helping larger Shopify stores manage high-volume messaging while maintaining deliverability and regulatory standards.

Compared to ONE, which aims to cover many marketing features at a low entry cost, Attentive takes a more specialized and enterprise-focused approach, prioritizing performance, compliance, and scalability over breadth.

Key features:

• AI-powered SMS and email personalization, designed to tailor messages across the customer lifecycle
• Advanced list growth tools, including two step opt ins and subscriber acquisition flows
• Enterprise grade compliance support, with in house TCPA guidance and safeguards
• Campaign analytics and testing, including performance measurement and A B testing

Limitations:

• Pricing is not transparent and may be expensive for small or growing stores
• Setup and onboarding can feel heavy for teams without dedicated marketing resources

When this app is a good fit (and when it’s not):

Attentive is a strong fit for Shopify brands that send SMS at scale and need high levels of personalization, compliance support, and account management. For smaller stores or teams looking for a simpler and more affordable SMS setup, a lighter weight SMS marketing app may be a better choice.

6. Postscript

Price: Free to install with a trial. Paid plans include Growth at $100/month and Professional at $500/month, with SMS usage billed separately based on message volume.

Best for: Shopify brands that treat SMS as a primary revenue channel and send messages at high volume.

Postscript is an SMS first marketing platform built specifically for Shopify stores that rely heavily on text messaging to drive revenue. It focuses on helping brands manage large scale SMS campaigns, customer conversations, and compliance while maintaining strong deliverability during peak traffic periods.

Compared to Attentive, which emphasizes enterprise level personalization across SMS and email, Postscript takes a more SMS focused approach, prioritizing campaign execution, testing, and performance optimization within a single channel.

Key features:

• SMS first automation and campaign tools, designed for large scale messaging programs
• Two-way messaging and conversation management, supporting customer replies and engagement
• Built in compliance and opt in controls, helping brands manage consent and quiet hours
• A/B testing and performance reporting, allowing teams to optimize SMS campaigns over time

Limitations:

• Higher entry pricing compared to general purpose SMS tools
• Not designed to manage email and SMS together in a single platform

When this app is a good fit (and when it’s not): 

Postscript is a strong fit for Shopify brands that already see meaningful revenue from SMS and want to scale that channel with dedicated tools and testing capabilities. For stores that are just starting with SMS or prefer a combined email and SMS solution, a more flexible or lower cost platform may be a better choice.

7. Shopify Messaging

Price: Free to install and included with Shopify. No separate SMS marketing fees, as it is designed for customer messaging rather than marketing campaigns.

Best for: Shopify stores that want to reply to customer messages across channels from one inbox, not run SMS marketing campaigns.

Shopify Messaging is often considered the best free SMS app for Shopify for basic use cases. It is Shopify’s native messaging app that lets merchants manage conversations from chat, email, and supported messaging channels in one place. 

Its primary goal is to help stores respond to customer questions and support requests, rather than run promotional or automated SMS marketing campaigns. Compared to Postscript and other dedicated SMS marketing tools, Shopify Messaging focuses on customer support conversations, not revenue-driven SMS automation.

Key features:

• Unified inbox for customer messages, including chat and supported messaging channels
• Native Shopify integration, with direct access to orders and customer context
• Simple reply and conversation management, designed for support teams
• No setup complexity, since it is built and maintained by Shopify

Limitations:

• Does not support SMS marketing campaigns, automation, or promotional broadcasts
• Lacks segmentation, revenue attribution, and SMS specific compliance tools

When this app is a good fit (and when it’s not): 

Shopify Messaging is a good fit for stores that mainly need a central inbox to respond to customer questions and provide basic support. If your goal is to use SMS as a marketing channel for abandoned carts, promotions, or retention campaigns, a dedicated SMS marketing app is required.

The best SMS marketing app for Shopify is the one that matches your specific goals, budget, and messaging strategy. By understanding the strengths and limitations of each option above, you can choose a platform that supports your store’s growth in 2026.

SMS Marketing Best Practices for Shopify Stores

SMS can be one of the highest intent marketing channels for Shopify stores, but it also comes with higher expectations from customers. The best results come from using SMS thoughtfully, respecting consent, and focusing on moments where text messages add real value instead of noise.

1. Get permission first (opt in is mandatory)

Shopify merchants must only send SMS marketing messages to customers who have clearly opted in. This usually happens through checkout checkboxes, popup forms, or dedicated SMS signup pages. Avoid pre checked boxes or unclear language, as improper consent can lead to compliance issues and reduced deliverability.

2. Keep messages short and focused

SMS is not email. Shopify SMS messages should focus on one clear action, such as recovering a cart or announcing a limited offer. Short messages are easier to read, cost less to send, and perform better with mobile carriers.

3. Use clear and direct CTAs

Every SMS should clearly tell the customer what to do next, whether that is viewing their cart, completing a purchase, or claiming an offer. Clear CTAs remove friction and make it easier for customers to act immediately.

4. Send at the right time and control frequency

Timing matters more for SMS than for most other channels. Messages should be sent during reasonable local hours and aligned with high intent moments like abandoned carts or restocks. Sending too many SMS messages is one of the fastest ways to increase opt outs.

5. Offer exclusive value through SMS

SMS works best when it feels special. Shopify merchants should use SMS for early access, limited-time deals, or important updates rather than duplicating email campaigns. Exclusivity helps justify why customers stay subscribed.

6. Make opt-out easy and visible

Every marketing SMS must include a simple opt-out option, such as “Reply STOP to unsubscribe.” Making it easy to leave helps maintain a healthier list and reduces the risk of spam complaints.

Following these best practices helps Shopify merchants use SMS as a sustainable marketing channel rather than a short-term tactic. When consent, timing, and value are handled correctly, SMS can support higher engagement without hurting trust or deliverability.
