What it does

Sample subheading — replace

Klaviyo is an email and SMS marketing platform built almost exclusively for online stores. It connects directly to Shopify and other ecommerce platforms, pulls in purchase history and cart activity, then uses that data to trigger messages automatically.

The clearest example is the abandoned cart flow: someone adds a product, leaves without buying, and Klaviyo sends a reminder a set number of hours later. The same pattern applies to post-purchase follow-ups and win-back messages for lapsed customers.

SMS is priced and billed separately from email, tiered by monthly message volume, which makes the total bill harder to predict than a flat subscription.

Who this helps

Sample subheading — replace

An online store that wants abandoned cart and post-purchase emails tied directly to order data.

A brand that wants email and SMS messaging combined in one platform instead of two.

A growing ecommerce business that has outgrown a general email tool and needs purchase-triggered automation.

A Shopify-based store that wants flows to run without manual campaign sends.
