Native Shopify Messaging
Shopify Messaging sends native SMS campaigns directly from your Shopify admin. United States marketing messages cost $0.012 per message, and a $2.15 monthly charge applies to each approved toll-free number used for SMS marketing. Longer messages split into multiple segments. Automated messages are also billed per SMS message (Shopify pricing).
These SMS charges do not include the Shopify store subscription itself. A United States toll-free sender cannot receive customer replies, so customers cannot text the campaign number back (Shopify setup). The documented United States SMS scope excludes Puerto Rico (Shopify requirements).
If receiving replies matters to your workflow, our customer service texting research covers apps built for two-way conversations (customer service texting).
How SMS billing differs
No single rate compares these apps because each provider prices a different thing. Klaviyo now uses per-message dollar rates tied to your account, while its app listing still shows an older credit-based price (Klaviyo pricing change, app listing).
Omnisend bills a Pro subscription that scales with contact count plus a separate SMS dollar balance (Omnisend plans, SMS credits). Sendlane shows a headline per-credit rate and a separate bundle table, so a package quote is needed to confirm which applies (Sendlane pricing).
Postscript combines usage with a platform fee or minimum, not a minimum plus usage on top (Postscript listing, billing FAQs). Attentive sets messaging rates inside a contract (Attentive billing FAQs). Numeric prices appear in the reviews below.
Shopify SMS workflows
Attentive syncs subscribers bidirectionally when people opt in through Attentive or Shopify, triggers order confirmation, shipping and arrival journeys, and can integrate, create or replenish Shopify discount codes (Attentive integration, Attentive review). Postscript personalizes campaigns and automations using historical Shopify data (Postscript listing, Postscript review).
Klaviyo offers Shopify order updates on paid accounts, with each message approved by Klaviyo first (Klaviyo order updates, Klaviyo review). Sendlane recommends upgrading to a paid plan before integrating and can populate unique regenerating coupon codes in SMS messages (Sendlane integration, Sendlane coupons, Sendlane review).
Omnisend also provides ready-made templates for creating and sending SMS campaigns from its Shopify listing (Omnisend listing, Omnisend review).
Shopify SMS questions
Is a free Shopify SMS app installation the same as free SMS?
No. Installation and sending are separate costs in every documented case. Postscript lists no platform fee on its entry tier but still applies a $49 monthly minimum spend, per its Shopify listing read October 23, 2026. Native Shopify Messaging sends from your Shopify admin but bills $0.012 per US message, per its pricing page.
Can customers reply to Shopify native SMS?
No. Shopify's setup guide read October 23, 2026 states you cannot receive customer replies to your toll-free sender number. The provider still bills the automated keyword responses it sends. Reply-dependent workflows need a provider that documents two-way messaging, and the customer service texting guide covers those options.
Do Klaviyo credits equal dollar rates?
Not across all accounts. Klaviyo moved Mobile Messaging from credits to per-message dollar rates starting July 13, 2026, per its transition page read October 23, 2026, and plans are still purchased upfront with no rollover. Its Shopify listing still shows $15 per month up to 1,250 credits. Confirm which system your account uses before estimating cost.
Do legacy Omnisend accounts keep their old pricing?
Partly. Omnisend will move Legacy Pro accounts to the current Pro plan on October 26, 2026, per its credits guide read October 23, 2026, and that move is announced rather than completed. Unused Legacy Pro credits carry over until 60 days after their original issue date. Standard or Free legacy subscriptions can remain if kept active, and new buyers sign up on current Pro terms.
