Klaviyo

Klaviyo is an email and SMS platform built around ecommerce data. It connects to the store, pulls orders, products and browsing events, and uses them to trigger automated flows such as abandoned cart, browse abandonment, welcome series, back in stock and win-back messages.

For conversion work, the abandoned cart and checkout flows are usually the first things a store sets up, because they reach people who were close to buying. Segments built from purchase history let you change the message, the timing or the offer for first-time visitors and regular customers. AI features help write subject lines and predict next order dates.

Watch your sending costs as your list grows, and clean out inactive profiles. Check that email and SMS consent is collected properly, especially for text messages, which have stricter rules. Test flow timing instead of copying a template, since the right delay depends on your products.
