Best Klaviyo Alternatives in 2026
Klaviyo is still the best ecommerce SMS platform, and still wrong for plenty of stores. Postscript wins on SMS-only economics, Brevo on price at $9/mo, Sendlane when the contact bill has outgrown the revenue.
Rankings reflect documented features, public pricing as of the "Last Updated" date, and category positioning analysis. We apply a Commercial Gate: only tools we can earn a commission from (now or in the next 12 months) enter the ranking pool. When a non-monetizable tool is the right answer, we name it with a caveat.

Postscript
Klaviyo remains the pick for ecommerce SMS overall, and this page is not an argument against it. It is the answer to a narrower question: what to move to when Klaviyo is the wrong fit. Postscript wins for stores that want SMS without paying for an email platform they do not use, and its usage-based pricing does not charge for contacts who never buy. Brevo at $9 a month is the value pick for anyone outside ecommerce who needs email and SMS without Shopify-shaped assumptions. Sendlane is the answer once Klaviyo's contact-based billing has visibly outgrown the revenue the list produces.

How This Was Tested
Pricing reflects published entry-tier list prices as of August 2026. SMS costs are excluded from headline figures across all platforms because carrier fees are billed separately and vary by country and message volume. Contact-based and send-based pricing models are compared at the point where they diverge rather than at their entry tiers, since the entry tier rarely reflects what a growing list costs.
Frequently Asked Questions
Postscript for Shopify stores that want SMS without paying for an email platform alongside it, because usage-based pricing means dormant contacts cost nothing. Brevo at $9 a month for businesses outside ecommerce. Sendlane for stores that want the same unified email and SMS model but better pricing above roughly 20,000 contacts.
Almost always the pricing model rather than the product. Klaviyo bills on stored contacts, so a list grows more expensive whether or not it produces revenue, and a store with a large inactive segment pays for people who will never buy again. The second reason is paying for a combined email and SMS platform while only using one half.
Yes. Brevo starts at $9 a month and prices on sends rather than contacts. Postscript is free to install with usage-based pricing from around $25. Both are materially cheaper than Klaviyo for a large list with a small active segment. Sendlane is not cheaper at the entry point and only wins above roughly 20,000 contacts.
Look at the ratio of contacts to buyers before deciding. Contact-based pricing punishes a list that grows faster than it converts, which is the usual pattern after a giveaway or a viral moment. If active buyers are a small fraction of stored contacts, usage-based pricing on Postscript or send-based pricing on Brevo will cost less. If most of the list buys, Klaviyo is priced fairly.
The unified customer profile. Klaviyo's advantage is that email and SMS share one view of the customer, so segmentation and suppression work across both channels automatically. Split them across two tools and that has to be maintained manually, which in practice means occasionally messaging someone on SMS who just bought via email. For stores where SMS is the dominant channel that trade is usually worth it.
Yes, and this page does not change that. Klaviyo remains the overall pick for ecommerce SMS because the unified profile and the depth of the ecommerce integrations are genuinely ahead. Being the best platform in a category is not the same as being the right platform for every business in it, and the alternatives here exist for specific mismatches rather than as a general improvement.
