Klaviyo is an email and SMS marketing platform built for ecommerce stores, syncing directly with store data (orders, browsing history, product catalog) rather than working off a generic contact list.
It solves lifecycle and post-purchase marketing for online stores: abandoned cart flows, back-in-stock alerts, win-back sequences, all triggered off real order data instead of just email opens. SMS and WhatsApp run in the same platform, so a Shopify store can send cart-recovery texts without a second tool.
Ecommerce brands on Shopify, WooCommerce, or BigCommerce that need revenue-attributed email/SMS flows. Not a fit for a service business with no product catalog to sync against.
The free plan runs indefinitely at up to 250 profiles, 500 email sends a month, and $5 of mobile messaging credit, enough to build and test a few flows on a small list before contact count forces an upgrade (paid tiers start around $20/month at 500 profiles).
