Best SMS marketing app for Shopify and Shopify SMS apps compared by real cost

Most "best Shopify SMS apps" lists rank tools by features. The better question is what your texts are for, because that decides what you pay.

• SMS is a campaign channel for you. Launches, drops and weekly promo texts to a big list. Postscript is built for that on Shopify. Attentive fits large brands with a managed program.
• Email is the center and SMS is an add-on. Klaviyo, or Omnisend Pro, keeps both in one place, priced by contacts with text credits on top.
• You only text abandoned carts, and not many. A pay-per-text tool such as CartBoss, or Postscript Starter with its 49 USD minimum spend.
• Recovery texts bring in most of your SMS revenue, and they keep growing. A recovery platform with texts included and a decision per cart. That is what we built CartAbandon for. See the abandoned cart text and SMS page.

One update many 2026 lists still miss: Yotpo shut down its SMSBump email and SMS product on December 31, 2025. If a guide still recommends it, the guide is out of date.

Prices come from each vendor's public pricing page where one exists, and otherwise from recent third-party pricing guides. They change often, so check before you buy.

A text at 0.008 USD sounds like nothing. The bill comes from three lines stacked together: the plan fee, the message fee and the carrier fee, which Postscript lists at about 0.0033 USD per US SMS on average and about 0.008 USD per MMS.

Take a Shopify store sending 3 000 abandoned cart texts and 6 000 campaign texts a month on Postscript Growth. That is 100 USD for the plan, 72 USD in message fees and about 30 USD in carrier fees, so roughly 202 USD a month. Switch half the campaign texts to MMS with a product image and the message and carrier fees climb quickly, because MMS costs several times more per send.

Now split the job. If campaigns stay in your SMS tool and the 3 000 recovery texts move to a plan where texts are included, the campaign bill shrinks and the recovery cost stops moving with traffic. On CartAbandon Scale those 3 000 texts sit inside 399 USD per month, or 199 USD billed yearly, together with 4 000 WhatsApp messages, recovery email and web push.

The number that matters is cost per recovered order. Take what you spend on cart texts in a month and divide it by the orders those texts brought back. Anything above a few dollars per order on a 60 USD average cart is worth a second look.

Campaign texts go to a list. Recovery texts go to one shopper about one cart, and that changes what a good tool does.

Timing per shopper

A recovery text works best within the first hour, but not at 2 a.m. in the shopper's time zone. Campaign tools schedule sends for the list. Recovery tools need quiet hours per contact.

A choice between text and email

Not every cart deserves a text. A 30 USD cart from a first-time visitor may close just as well from an email that costs nothing extra. The AI cart recovery decision engine picks the channel per cart, so texts go where they pay.

No reflex coupon

Promo texts carry offers by design. Recovery texts often should not, because a returning customer who left to check shipping was coming back anyway. CartAbandon sets a maximum discount and a minimum margin, and only offers a code when a cart needs one.

Replies from real shoppers

Shoppers answer recovery texts with questions about sizes, shipping dates and returns. If your team cannot answer them fast, an AI customer service assistant that answers and qualifies messages can take the first reply so a ready buyer is not left waiting.

What is the all-in cost per text?

Add the message fee, the carrier fee and any MMS premium. Some pricing pages show only the message fee.

Is there a minimum spend or a contract?

Minimum monthly spends and annual commitments set your floor even in a slow month. Ask for both in writing.

Does it take a percent of recovered revenue?

Some cart recovery add-ons bill a share of the sales they claim. TxtCart, for example, lists 10 percent of recovered sales for its P2P cart recovery add-on.

How does it handle consent?

US texting rules expect clear opt-in, a working STOP reply and quiet hours. Make sure the app records where and when each shopper agreed.

Does it work outside Shopify?

If you also run a WooCommerce or Magento store, check platform support. Several SMS apps are Shopify only. CartAbandon covers all three, see the Shopify abandoned cart app page for setup.

CartAbandon fits Shopify, WooCommerce and Magento stores where abandoned cart, abandoned checkout and declined card texts bring in most of the SMS revenue, and where a bill that grows with every text has started to hurt. Texts, WhatsApp from Growth, recovery email and an exit-intent offer share one flat plan, and declined cards get a payment update link instead of a coupon. Read about dunning software for failed payment recovery for that part.

It is not the right fit if you want to send SMS campaigns, run text-to-join keywords or build a promo list. We do not do that. Many stores keep a campaign tool for promos and move recovery to us. If you are weighing that today, our Postscript alternative and Klaviyo alternative pages show the side-by-side numbers.
