What is Klaviyo?

Klaviyo is email and SMS marketing built for online stores, and its real asset is the data model: it pulls order history, browsing and product events into one profile, then lets you build segments and flows from that. Machine learning appears in the predictive properties attached to each profile - expected date of next order, predicted customer lifetime value, churn risk - which can be used as conditions in an automation, plus send-time optimisation and subject line suggestions. Journeys themselves are rules you design, so it rewards merchants who will actually build and maintain them.

FAQ

Which parts are genuinely predictive?

The property fields attached to each profile: expected next order date, predicted lifetime value and churn risk. They come from models trained on store data, and they are what allow a flow to branch on future behaviour rather than past clicks.

Is it only for Shopify stores?

Shopify is the most common integration, but Klaviyo connects to other commerce platforms and custom data sources. The more of your order and browsing data it receives, the more the segmentation is worth.

Why does the bill grow so fast?

Pricing follows contact count, including people who never open anything. Regular list cleaning and suppression of unengaged profiles is the standard way to keep costs proportionate.
