8 Best SMS Marketing Software for Ecommerce in 2026

Attentive earns the top spot for large ecommerce stores because it turns purchase history into SMS segments without manual list work. Its AI builds audiences from what customers bought, how much they spent and when they last ordered, then personalizes each text from that data. Managed onboarding and deliverability support come with the account, which suits a store that wants the program run for it.

The catch is the price and the sales process. Attentive publishes no prices: you book a demo, get a custom quote, and sign a contract with quarterly minimums. Public contract data puts the median annual deal near $40,000. A store doing under $200,000 a month will pay far more here than on Postscript or Klaviyo for the same messages.

Postscript is the best pick for a Shopify store that wants every text tied to a real order event. It reads live order, product and customer data, so abandoned-checkout, back-in-stock, shipping and delivery texts trigger from store events without extra setup. Starter has a $0 platform fee with a $49 monthly minimum spend, and US SMS costs $0.009 per message plus carrier fees.

The catch is the single-platform limit and the minimum spend. Postscript works only on Shopify, so a store that also sells on WooCommerce or Amazon must run a second tool for those orders. You also pay $49 a month even in a month when you send nothing, and a dedicated short code costs $750 a month extra.

Klaviyo is the best pick for an ecommerce store that sells on more than one platform. It links Shopify, WooCommerce, BigCommerce and Magento orders to email and SMS flows, and it shows revenue per flow, so you can see which texts and emails drove orders. Flows switch between email and SMS based on what each customer opens, and the free plan covers 250 profiles, 500 emails and $5 of mobile messages a month.

The catch is the price curve. The Email plan starts at $20 a month for 251 to 500 profiles, Email plus SMS starts at $35 a month, and the bill climbs with every new active profile. SMS credits cost extra on every tier, and free-plan email support ends after 60 days. Model the price at 1,000 and 5,000 profiles before you commit.

Omnisend is the cheapest paid pick for a small ecommerce store that wants email and SMS together. Standard starts at $16 a month for up to 500 contacts with 6,000 emails, and the free plan covers 250 contacts and 500 emails a month. It links Shopify, WooCommerce and BigCommerce orders to flows, and every plan includes automation, segmentation and A/B testing.

The catch is that SMS is not a Standard feature for new accounts. Plans started after May 4, 2026 need Pro at $59 a month to buy SMS credits, which start at $0.007 per message in the US, and revenue per flow shows on Pro as well. A store that only wants SMS will pay $59 a month here, while a store that wants email plus SMS gets a fair deal.

SimpleTexting suits an ecommerce store that wants SMS only, with no tier puzzle. It starts at $39 a month for 500 credits with a local number included, and every feature ships on every plan: automations, API access, AI writing help and unlimited keywords. Contacts sync from the store, and three user seats are included, so the owner and two staff can share the account.

The catch is the thin store link. SimpleTexting syncs contacts but does not read live order or product data, so cart and back-in-stock texts need a third-party app to trigger them. There is also no email channel and no revenue attribution, so a store that wants to see orders per text must track them elsewhere.

SlickText is the best pick for an ecommerce store that sends in bursts around sales and launches. It starts at $29 a month for 500 credits, and unused credits roll over to the next month, so a quiet month banks credit for a big sale. Every plan includes unlimited users, unlimited contacts, all automation features and every integration, so the whole team can run campaigns from one account.

The catch is the same thin store link. SlickText syncs contacts but does not read live order data, so product-triggered texts need a third-party app. It is also SMS-only, with no email channel and no revenue attribution. A store that wants to see orders per text should pair it with a separate analytics check.

TextMagic suits an ecommerce store that texts rarely and sells to customers abroad. It charges $0.049 per SMS in the US on a pay-as-you-go basis, with credits that never expire, and it covers 190 countries, so one account can text buyers in many markets. Two-way chat and scheduling are included, which covers order questions and delivery updates.

The catch is the number rent and the missing store features. A virtual number costs $10 a month, and 10DLC campaign registration costs another $10 a month, so the real floor is about $20 a month before you send a text. There is no native store link, no revenue attribution and few marketing templates, so it fits alerts better than campaigns.

Brevo suits an ecommerce store that sends email most days and texts only for flash sales or back-in-stock alerts. Starter costs $9 a month for 5,000 emails, and the free plan sends 300 emails a day. SMS credits are sold separately on a pay-as-you-go basis, so a store that texts rarely pays only for the messages it sends, and the account also covers WhatsApp and a basic CRM.

The catch is that SMS is a side channel here. The SMS tools are thinner than on a dedicated SMS platform, with fewer templates and no SMS-first automation library, and the store link is lighter than Klaviyo's. Automation and A/B testing also need Standard at $18 a month, and the Brevo logo stays on Starter emails unless you pay for removal.
