Klaviyo

The data rich email and SMS platform built for ecommerce, where deep store data turns into precise, profitable sends.

Klaviyo is what serious online stores graduate to. It plugs directly into Shopify, BigCommerce and the rest, pulls in order and browsing data, and turns it into granular segments, predictive analytics and revenue attribution that most rivals cannot match. Email and SMS share one profile, so flows like abandoned cart and post purchase run across channels. The catch is fit and cost: pricing follows active profiles and climbs quickly, the depth is overkill for a simple newsletter, and non ecommerce teams pay for power they may never use.

The scorecard

Features and integrations lead, value is the question.

Klaviyo scores highest where ecommerce teams need it most, in data depth and store integrations. Value lands mid pack because the active profile model gets expensive as you scale.
