10 Best SMS Marketing Apps for Shopify (2026)

We have implemented, tested, and managed SMS marketing campaigns across our Shopify client stores using these platforms. Here are our picks for the best SMS marketing apps for Shopify in 2026, with honest assessments of what each does well and who they suit best.

1. Klaviyo

• Price: Free up to 250 contacts; SMS from $15/month
• Shopify Rating: 3.9/5 (1,723+ reviews)
• Best For: Shopify stores wanting unified email and SMS marketing in one platform
• Free Trial: Free plan available

Klaviyo is our top recommendation for SMS marketing on Shopify, and it is the platform we implement most frequently for our clients at Charle. The reason is straightforward: Klaviyo brings email and SMS into a single platform with the deepest Shopify integration available. This means your email and SMS campaigns share the same customer data, segments, and automation flows rather than operating in silos.

The Shopify integration is best-in-class. Klaviyo syncs over 200 data points from your Shopify store in real time, including browsing behavior, purchase history, cart activity, and customer lifetime value. This data powers highly targeted SMS campaigns. You can send abandoned cart texts to customers who left items worth over $100, trigger post-purchase follow-ups based on specific products, or segment VIP customers for exclusive SMS-only offers.

Klaviyo's SMS automation flows are where the platform truly shines. You can build multi-step flows that combine email and SMS touchpoints based on customer behavior. A typical abandoned cart sequence might start with an email, follow up with an SMS two hours later if the email goes unopened, and send a final reminder the next day. This coordinated approach outperforms standalone SMS campaigns significantly.

The 3.9 Shopify rating deserves context. Klaviyo is a powerful, feature-rich platform that can feel overwhelming for beginners. The learning curve is steeper than simpler tools, and some merchants find the pricing complex as their lists grow. For stores serious about SMS marketing, the investment in learning the platform pays off considerably.

AI-powered features include predictive analytics that forecast customer lifetime value and churn risk, smart send time optimization that delivers messages when each customer is most likely to engage, and AI-generated subject lines and SMS copy suggestions.

Key features: Unified email + SMS platform, 200+ Shopify data points, multi-step automation flows, predictive analytics, A/B testing, smart send time, advanced segmentation, GDPR and TCPA compliance tools.

Why choose Klaviyo: If you want email and SMS marketing working together seamlessly with the deepest Shopify data integration available, Klaviyo is the clear market leader. It is particularly strong for stores already using Klaviyo for email who want to add SMS without managing a separate platform.

2. Attentive

• Price: Custom pricing (typically enterprise)
• Notable Clients: Coach, Urban Outfitters, CB2, Supergoop
• Best For: Mid-market to enterprise brands wanting a dedicated SMS-first platform
• Free Trial: Demo available

Attentive is the enterprise leader in SMS marketing and a platform that most Shopify-focused competitor articles overlook entirely. If your store has outgrown basic SMS tools and needs a dedicated platform with advanced personalization, Attentive delivers capabilities that all-in-one tools cannot match.

The subscriber acquisition tools are where Attentive separates itself from the competition. Their patented two-tap sign-up technology makes it remarkably easy for mobile visitors to opt in to SMS. The platform also offers a wide range of sign-up units including pop-ups, embedded forms, checkout opt-ins, and social media integrations. Attentive claims their sign-up tools convert 30% better than industry averages.

Attentive's segmentation and personalization capabilities are enterprise-grade. You can build segments based on real-time behavioral data, purchase history, engagement patterns, and custom events. The platform then uses AI to determine optimal send times, message frequency, and content for each subscriber segment.

The Shopify integration connects order data, product catalog, and customer information into the Attentive platform. Agents can trigger messages based on Shopify events like order confirmation, shipping updates, and back-in-stock notifications alongside marketing campaigns.

Attentive's Concierge feature enables two-way conversational SMS, allowing customers to reply to messages and interact with your brand through text. This turns SMS from a broadcast channel into a genuine conversation tool that drives engagement and sales.

Key features: Patented two-tap sign-up, AI-powered personalization, advanced segmentation, two-way conversational SMS, A/B testing, journey builder, compliance management, real-time analytics.

Why choose Attentive: If SMS is a primary revenue channel for your brand and you need enterprise-grade subscriber acquisition, segmentation, and personalization, Attentive is purpose-built for serious SMS marketers.

• Shopify Rating: 4.9/5 (1,631+ reviews)
• Best For: Shopify stores wanting an SMS-only specialist with top-tier Shopify integration
• Free Trial: Free plan with pay-as-you-go messaging

Postscript is built exclusively for Shopify SMS marketing and nothing else. That singular focus shows in every aspect of the platform. With a 4.9 rating from over 1,631 reviews, it is the highest-rated dedicated SMS app on the Shopify App Store.

The Shopify integration is native and deep. Postscript uses Shopify data to power targeted campaigns and automations based on purchase history, browsing behavior, cart activity, and customer tags. You can create segments like "customers who bought product X but not product Y" or "subscribers who clicked an SMS link in the last 30 days" with ease.

Postscript excels at conversational SMS. Their platform enables genuine two-way text conversations between your brand and customers, not just one-way blasts. This conversational approach drives higher engagement rates because customers can reply, ask questions, and interact naturally. The Sales team feature lets human agents jump into automated conversations when a personal touch is needed.

The pricing model is refreshingly transparent. There is no monthly platform fee on the starter plan. You only pay for messages sent, with costs varying by message type and volume. This makes Postscript accessible to smaller stores that want to test SMS without committing to a monthly subscription.

Compliance is baked into everything Postscript does. The platform handles TCPA compliance, quiet hours, opt-out management, and consent tracking automatically. Their subscriber acquisition tools (pop-ups, keywords, checkout opt-ins) are all pre-configured for compliance.

Key features: Shopify-native SMS, two-way conversational messaging, pay-per-message pricing, automated flows, advanced segmentation, compliance management, A/B testing, revenue attribution.

• Shopify Rating: 4.8/5 (5,233+ reviews)
• Best For: Stores wanting email, SMS, and push notifications in one affordable platform
• Free Trial: Free plan with 60 SMS credits/month

Omnisend is the most popular marketing automation platform on the Shopify App Store by review count, with over 5,233 reviews and a 4.8 rating. It combines email, SMS, and push notifications into a single platform at a price point that undercuts Klaviyo for many store sizes.

The SMS capabilities are tightly integrated with email workflows. You can add SMS steps to any automation flow, letting you reach customers through their preferred channel at the right moment. The platform includes pre-built automation workflows for abandoned carts, welcome series, order confirmations, and shipping updates that combine email and SMS touchpoints.

Omnisend's free plan includes 60 SMS credits per month, which is enough to test the channel before committing to a paid plan. The Standard plan at $16 per month includes more generous SMS credits and unlocks advanced features like 24/7 priority support and advanced reporting.

For stores that want multi-channel marketing without managing multiple tools, Omnisend offers strong value. The campaign builder lets you create coordinated campaigns across email, SMS, and push notifications from a single interface.

5. TxtCart

• Price: Free to install (pay per conversion)
• Shopify Rating: 4.7/5 (300+ reviews)
• Best For: Stores wanting AI-powered cart recovery with performance-based pricing
• Free Trial: 14-day free trial

TxtCart takes a unique approach to SMS marketing by focusing almost entirely on abandoned cart recovery through AI-powered conversational text messages. Rather than sending generic "you left something in your cart" blasts, TxtCart uses AI to have genuine two-way conversations with customers who abandon checkout.

The AI agent responds to customer replies in real time, answers questions about products, addresses objections, and can offer dynamic discounts to close the sale. This conversational approach typically recovers significantly more carts than static abandoned cart SMS messages because it mimics the experience of chatting with a helpful shop assistant.

The pricing model is performance-based, which sets TxtCart apart from every other app on this list. You pay a percentage of recovered revenue rather than a flat monthly fee or per-message cost. This means TxtCart only costs you money when it makes you money. For stores unsure about SMS ROI, this zero-risk model is compelling.

Setup is quick and straightforward. Connect your Shopify store, configure your discount rules and brand voice preferences, and TxtCart starts recovering carts automatically. The AI adapts to your brand tone and can be customized to match how you communicate with customers.

Key features: AI-powered conversational cart recovery, performance-based pricing, real-time two-way SMS, dynamic discount offers, brand voice customization, Shopify integration, revenue analytics.

Why choose TxtCart: If abandoned cart recovery is your primary goal and you want a zero-risk performance-based pricing model, TxtCart's AI conversations recover more carts than traditional SMS blasts.

6. Recart

• Price: From $299/month
• Shopify Rating: 4.8/5 (400+ reviews)
• Best For: Brands wanting a done-for-you managed SMS service
• Free Trial: Demo available

Recart offers something genuinely different from every other app on this list: a fully managed SMS marketing service. Rather than giving you a platform and leaving you to figure it out, Recart assigns a dedicated SMS strategist to your account who builds campaigns, writes copy, manages automations, and optimizes performance on your behalf.

This done-for-you approach solves the biggest problem with SMS marketing for many Shopify stores: lack of time and expertise to do it properly. Most stores install an SMS app, set up a basic abandoned cart flow, and never touch it again. Recart's managed service ensures your SMS program is continuously optimized by someone who does this full-time.

The platform itself is built specifically for Shopify and focuses exclusively on SMS. The subscriber acquisition tools include a two-tap pop-up that makes mobile opt-ins frictionless, plus checkout opt-ins, landing pages, and keyword sign-ups. Recart claims their pop-ups convert at 8 to 12% on average.

The premium price point of $299 per month reflects the managed service element. You are not just paying for software; you are paying for a dedicated strategist. For stores generating significant revenue where SMS could drive meaningful uplift, the return on investment typically justifies the cost within the first month or two.

Key features: Dedicated SMS strategist, done-for-you campaign management, high-converting pop-ups, two-tap opt-in, Shopify-native integration, automated flows, compliance management, performance reporting.

Why choose Recart: If you want expert-level SMS marketing without hiring an in-house specialist or spending hours learning a platform, Recart's managed service delivers results while you focus on running your business.

7. Emotive

• Price: Custom pricing (typically from $100/month)
• Best For: Brands wanting human-powered conversational SMS
• Free Trial: Demo available

Emotive takes a unique approach by combining AI with real human agents for conversational SMS marketing. Instead of automated one-way blasts, Emotive's team of trained conversation specialists (backed by AI) engage in genuine two-way text conversations with your customers. They handle abandoned cart recovery, product recommendations, and promotional campaigns through natural conversation.

The human element is what sets Emotive apart. While other platforms automate SMS messaging, Emotive's trained specialists craft personalized responses that feel genuinely human, not robotic. This conversational approach typically converts better than automated templates because customers respond positively to authentic communication. The AI assists by suggesting responses and handling routine tasks, but real people drive the conversations.

The Shopify integration pulls in order and product data, allowing Emotive's specialists to make informed, contextual recommendations. They understand the full customer journey and can offer product suggestions, upsells, and promotions that feel natural within the conversation.

Emotive is particularly popular with mid-market direct-to-consumer brands that want SMS marketing but lack in-house expertise. Instead of hiring a specialist or struggling with platform complexity, you get a managed conversational SMS service where real strategists handle customer conversations on your behalf.

Key features: Human + AI conversational SMS, abandoned cart recovery, campaign management, Shopify integration, dedicated strategist, analytics, personalized product recommendations, real-time two-way messaging.

Why choose Emotive: If you believe real human conversations convert better than automated messages and want a managed conversational SMS service without the complexity of hiring in-house expertise, Emotive delivers authentic customer engagement through professional conversation specialists.

8. Privy

• Price: Free plan available; SMS from $30/month
• Shopify Rating: 4.6/5 (24,805+ reviews)
• Best For: Stores wanting best-in-class list building pop-ups combined with SMS
• Free Trial: 15-day free trial on paid plans

Privy is the most widely installed marketing app on Shopify with a staggering 24,805+ reviews. While it started as a pop-up and email capture tool, Privy has evolved into a solid SMS marketing platform, particularly for stores that prioritize subscriber list growth.

The pop-up and display builder is where Privy excels above all competitors. You can create spin-to-win wheels, exit-intent pop-ups, welcome discounts, free shipping bars, and embedded forms that capture both email addresses and phone numbers simultaneously. The A/B testing for pop-ups is comprehensive, letting you test different designs, copy, offers, and triggers to maximize conversion rates.

SMS capabilities include automated abandoned cart texts, welcome series, after-purchase follow-ups, and one-off campaign broadcasts. The SMS features are not as deep as Klaviyo or Postscript, but they cover the essentials well and are easy to set up without technical expertise.

For smaller Shopify stores that need to build their subscriber list quickly and want a simple SMS tool alongside that list building, Privy offers an effective combination at a reasonable price. The free plan covers basic pop-ups and email, with SMS available from $30 per month.

Key features: Industry-leading pop-up builder, A/B testing, spin-to-win, exit-intent displays, SMS automations, cart abandonment texts, coupon management, Shopify integration.

Why choose Privy: If growing your SMS subscriber list is the priority and you want the best pop-up and display tools available, Privy's list building capabilities are unmatched in the Shopify ecosystem.

9. Sendlane

• Price: From $83/month
• Notable Clients: Ecommerce brands doing $1M+ in revenue
• Best For: Established stores wanting advanced SMS and email automation
• Free Trial: 14-day free trial

Sendlane positions itself as the email and SMS platform for serious ecommerce brands. Their focus on deep data integration and advanced automation makes them a strong choice for established Shopify stores that have outgrown basic marketing tools.

The SMS automation capabilities are sophisticated. Sendlane's multivariable segmentation lets you create highly targeted audiences based on combinations of purchase behavior, email engagement, SMS engagement, website activity, and custom properties. This means you can send different SMS messages to customers based on exactly where they are in their buying journey.

The real-time event tracking is a standout feature. Sendlane tracks customer behavior as it happens and can trigger SMS messages instantly based on specific actions. If a customer views a product three times without purchasing, you can automatically send a targeted text with a personalized offer for that exact product.

Sendlane's unified email and SMS platform ensures both channels work together rather than competing. The automation builder lets you create complex flows that intelligently switch between email and SMS based on customer preferences and engagement patterns.

Key features: Advanced automation builder, real-time event tracking, multivariable segmentation, unified email + SMS, deep Shopify integration, revenue attribution, deliverability optimization.

Why choose Sendlane: If your store generates significant revenue and you need advanced automation with deep data-driven segmentation across email and SMS, Sendlane is built for brands that take marketing seriously.

10. Twilio

• Price: Pay-as-you-go (from $0.0079/message)
• Best For: Technical teams wanting complete SMS control
• Free Trial: Free account with $15 credit

Twilio is not a traditional Shopify SMS marketing app. It is a programmable messaging API that gives developers complete control over SMS communication. For Shopify stores with technical teams, Twilio offers unmatched flexibility to build custom SMS workflows, integrations, and messaging experiences that no off-the-shelf app can replicate.

Several Shopify apps on this list (including Postscript) are built on Twilio's infrastructure. If you have development resources, you can build exactly the SMS experience your store needs without being limited by platform constraints. The possibilities include abandoned cart flows, transactional messaging, two-way conversations, and custom automations tailored exactly to your business needs.

The trade-off is that Twilio requires development resources to implement and maintain. You are not buying a ready-made solution; you are buying the underlying infrastructure to build your own solution. This is ideal for engineering teams that want complete control and are willing to invest development time. It is not ideal for non-technical merchants looking for a plug-and-play tool.

Twilio's pricing is straightforward and transparent: you only pay for messages sent. At $0.0079 per message for standard SMS in the United States, costs are competitive with other platforms, and you have complete visibility into what you are paying for.

Key features: Programmable SMS API, global reach (180+ countries), custom workflow building, MMS support, two-way messaging, deliverability optimization, pay-per-message pricing, webhooks for real-time updates.

Why choose Twilio: If your team has development resources and you want complete control over your SMS infrastructure without platform limitations, Twilio is the ideal choice for building custom SMS experiences at scale.

Why SMS Marketing Matters for Shopify Stores

SMS marketing has become one of the most effective channels for Shopify stores, and the numbers explain why. Text messages have open rates above 90%, compared to 20 to 25% for email. Click-through rates for SMS typically range from 20 to 35%, dwarfing the 2 to 3% average for email campaigns. These are not marginal improvements; they represent a fundamentally different level of customer engagement.

The immediacy of SMS is what makes it so powerful for ecommerce. Most text messages are read within three minutes of delivery. For time-sensitive promotions, flash sales, back-in-stock alerts, and abandoned cart recovery, that immediacy translates directly into revenue. A customer who receives a cart abandonment text within an hour is far more likely to complete their purchase than one who receives an email the next day.

SMS also reaches customers in a space where competition is lower. Most people receive dozens or hundreds of marketing emails daily, but relatively few marketing texts. This means your SMS messages get noticed in a way that emails increasingly cannot. The personal, direct nature of text messaging creates a sense of exclusivity that drives higher engagement.

Revenue per message for SMS consistently outperforms other marketing channels for the Shopify stores we work with at Charle. When implemented properly with the right platform and strategy, SMS typically generates 20 to 30% of total email marketing revenue as an additional channel. For a store already generating $50,000 per month from email, adding SMS can realistically drive an additional $10,000 to $15,000.

The combination of SMS with email marketing creates a powerful multi-channel approach. Email handles longer content, product education, and brand storytelling. SMS delivers urgent, time-sensitive messages that demand immediate action. Together, they cover the full spectrum of customer communication.

Essential Features in a Shopify SMS Marketing App

Not every SMS app offers the same capabilities. Here are the features that matter most when choosing an SMS marketing tool for your Shopify store.

Shopify integration depth determines how effectively you can target and personalize messages. Look for apps that sync Shopify order data, product catalogs, customer tags, and browsing behavior in real time. The deeper the integration, the more relevant your messages become. Klaviyo and Postscript lead here.

Automation flows are essential for consistent revenue from SMS. At minimum, you need automated abandoned cart recovery, welcome series for new subscribers, post-purchase follow-ups, and shipping notifications. Advanced platforms offer browse abandonment, winback sequences, and conditional logic that adapts flows based on customer behavior.

Subscriber acquisition tools determine how quickly you can build your SMS list. Pop-ups, checkout opt-ins, keyword sign-ups, and QR codes all help capture phone numbers. Some platforms like Attentive and Recart offer patented sign-up technologies that convert significantly better than standard forms.

Compliance management is non-negotiable for SMS marketing. In the United States, you must comply with TCPA and CAN-SPAM regulations. Your SMS platform must handle consent collection, opt-out processing, quiet hours, and data storage properly. Every app on this list handles compliance to varying degrees, but platforms like Postscript and Klaviyo make it nearly impossible to accidentally violate regulations.

Segmentation and personalization separate effective SMS campaigns from spam. The ability to segment audiences based on purchase history, engagement patterns, and customer value means you send relevant messages to the right people at the right time. Mass-blasting your entire list with identical messages wastes credits and annoys subscribers.

Revenue attribution proves SMS ROI to your business. Good platforms track exactly which messages, flows, and campaigns generate revenue, giving you clear data to optimize your strategy and justify your SMS investment.

How to Choose the Right SMS Marketing App

Choosing the right SMS app depends on your store's size, budget, existing tech stack, and how seriously you plan to invest in the channel.

If you already use Klaviyo for email, adding Klaviyo SMS is the obvious choice. You get unified data, coordinated automation flows, and a single platform to manage. The marginal cost of adding SMS to an existing Klaviyo account is significantly less than running a separate SMS platform.

If you want SMS only, Postscript is the standout Shopify specialist. Their singular focus on SMS means every feature is designed for text message marketing. The pay-per-message pricing model also means you do not pay anything until you start sending.

If budget is tight, Omnisend's free plan with 60 SMS credits or Firepush's free tier let you test SMS without financial commitment. TxtCart's performance-based pricing is another zero-risk option for abandoned cart recovery specifically.

If you are a larger brand, Attentive or Recart's managed service offer enterprise capabilities. Attentive provides the most advanced platform for serious SMS marketers. Recart removes the complexity entirely by managing everything for you.

If list building is your focus, Privy's pop-up tools are unmatched for capturing phone numbers. You can always collect subscribers with Privy and send messages through a more advanced SMS platform later.

Test before committing. Most apps on this list offer free plans or trials. Install your top two choices, run them for two weeks, and compare the experience. Pay attention to ease of use, Shopify integration quality, and how intuitive the automation builder feels.

SMS Compliance Guide for US Shopify Stores

SMS compliance is not optional. In the United States, sending marketing texts without proper consent can result in significant fines from the FCC and FTC. Here is what you need to know.

TCPA compliance is the foundation of US SMS marketing. The Telephone Consumer Protection Act requires you to obtain explicit consent before sending marketing SMS messages. Consent must be freely given, specific, and clearly disclosed. Customers must actively opt in, and you must clearly explain what types of messages they will receive and how often. You must also maintain records of when and how each subscriber gave consent.

Opt-out processing must be instant and hassle-free. Every marketing SMS must include a way to unsubscribe, typically by replying STOP. Your platform must process opt-outs immediately and permanently remove the number from marketing lists. All apps on this list handle this automatically.

Quiet hours should be respected as industry best practice. Avoid sending marketing messages before 8am or after 9pm in the recipient's local time zone. Most SMS platforms enforce quiet hours by default, but check your settings to confirm they align with your messaging strategy.

Record keeping matters. Maintain records of when and how each subscriber gave consent, what they consented to, and when they opted out. This documentation protects you if a complaint is made. Platforms like Klaviyo and Postscript maintain these records automatically.

Transactional vs marketing messages have different rules. Order confirmations, shipping updates, and delivery notifications are transactional and do not require marketing consent. Promotional offers, flash sales, and product recommendations are marketing messages and do require consent. Make sure your platform distinguishes between these correctly.

SMS Marketing Strategies That Work for Shopify

Having the right platform is only half the equation. Here are the SMS strategies that drive real revenue for the Shopify stores we work with at Charle.

Abandoned cart recovery is the highest-ROI SMS automation for most stores. Send the first text within one hour of cart abandonment, include the product name and image link, and consider offering a small incentive for first-time buyers. Keep the message short and include a direct link back to the cart. This single flow often generates 50% or more of total SMS revenue.

Welcome series set the tone for your SMS relationship. When a new subscriber opts in, send an immediate welcome text with the promised discount code. Follow up two to three days later with your brand story or best-selling products. This series converts subscribers into customers while engagement is highest.

VIP and loyalty messaging rewards your best customers through the most personal channel. Give SMS subscribers early access to new products, exclusive discount codes, or limited-edition drops. This exclusivity justifies the SMS channel and keeps opt-out rates low.

Back-in-stock alerts recover sales from previously sold-out products. Let customers sign up for text notifications when a specific product returns. These messages convert at extremely high rates because the customer has already expressed purchase intent.

Post-purchase flows build long-term customer value. Thank customers after their purchase, request reviews at the right moment, and cross-sell complementary products based on what they bought. A well-timed cross-sell text after a customer's order arrives can drive significant repeat revenue.

Frequency matters. Most successful Shopify stores send two to four marketing SMS messages per month alongside automated transactional flows. Over-messaging is the fastest way to drive opt-outs. Treat your SMS list as a premium channel and send only when you have something genuinely valuable to share.

SMS vs Email Marketing for Shopify

SMS and email are not competing channels. They are complementary, and the best results come from using both strategically. Here is how they compare and when to use each.

Open rates heavily favor SMS. Text messages achieve 90%+ open rates versus 20 to 25% for email. If you need a message seen, SMS wins by a significant margin.

Click-through rates are also higher for SMS, typically 20 to 35% compared to 2 to 3% for email. The direct, personal nature of text messaging drives action more effectively than email.

Content depth is where email excels. SMS messages are limited to 160 characters (or MMS for richer content), while email supports detailed product descriptions, multiple images, brand storytelling, and complex layouts. Use email for content that needs space; use SMS for urgent, action-oriented messages.

Cost per message is higher for SMS. A single text typically costs 0.5 to 3 cents depending on your platform and volume, while email is essentially free beyond the platform subscription. This means SMS should target high-intent segments where the higher cost delivers proportionally higher returns.

Frequency tolerance differs significantly. Subscribers accept daily emails but react negatively to daily texts. Limit SMS campaigns to two to four per month and reserve the channel for your most impactful messages.

The ideal approach uses email as your primary communication channel for regular newsletters, product launches, and content marketing. Use SMS for time-sensitive offers, abandoned cart recovery, flash sales, back-in-stock alerts, and VIP exclusives. Platforms like Klaviyo and Omnisend make coordinating both channels from a single automation flow straightforward.

Common SMS Marketing Mistakes on Shopify

We have seen these mistakes repeatedly across Shopify stores. Avoiding them will improve your SMS performance and keep your subscribers happy.

Sending too many messages. The fastest way to destroy your SMS list is over-messaging. Subscribers who feel bombarded will opt out permanently. Start with two to four marketing messages per month and only increase if your engagement metrics support it.

Ignoring segmentation. Sending the same message to your entire list wastes credits and annoys subscribers who receive irrelevant offers. Segment by purchase history, engagement level, and customer value. A first-time buyer should receive different messages than a five-time repeat customer.

Weak calls to action. Every SMS needs a clear, single action for the recipient. "Check out our new collection" is vague. "Get 20% off our new spring collection today only" with a direct link is specific and urgent. Include a link in every marketing text.

Not tracking attribution. If you cannot prove SMS revenue, you cannot justify the investment or optimize your strategy. Use a platform with built-in revenue attribution and review the data monthly. Know your cost per message, revenue per message, and overall channel ROI.

Treating SMS like email. Text messages are not short emails. They are personal, conversational, and immediate. Write in a casual, friendly tone. Use the customer's first name. Keep messages under 160 characters when possible. Drop the corporate formality that works in email newsletters.

Neglecting compliance. Sending texts without proper consent is not just risky; it is illegal. Ensure every subscriber has explicitly opted in, process opt-outs instantly, and respect quiet hours. One compliance violation can result in fines that dwarf any revenue SMS generates.
