Ecommerce email and SMS built on customer data — the category leader, at a price.
Pricing
Verified 14 Jul 2026· sourceOverview
Klaviyo is what happens when an email platform is designed around a customer data store rather than a mailing list. It ingests behavioural and transactional data from Shopify and other ecommerce platforms — what someone browsed, abandoned, bought, when they last returned — and lets you segment and trigger against it with real precision. That is why abandoned-cart, win-back and post-purchase flows perform so much better here than in general-purpose tools, and why it has become the default for serious direct-to-consumer brands. Email and SMS live in one system, and AI features cover predictive analytics, content generation and send-time optimisation. The cost is the story. Pricing scales on active profiles and sends, and it becomes genuinely expensive as your list grows — SMS is billed separately on top. The platform is powerful enough to be complicated, and small teams routinely use a fraction of what they pay for. Outside ecommerce, much of the value evaporates: if you're a B2B SaaS company or a newsletter, you are paying for machinery you will never switch on.
