Overview
Klaviyo is a B2C marketing platform built on a customer data platform, sending email, SMS and push from unified customer profiles. It carries automation flows, real-time segmentation with predictive analytics, a drag-and-drop editor, deliverability tools and deep ecommerce data, with more than 350 native integrations including Shopify and WooCommerce. Its AI features generate content and suggest subject lines and segments, and AI agents can draft and execute campaigns. Pricing is based on the number of active profiles, and paid email plans scale with the size of the audience.
Our take
Klaviyo earns its keep where a shop's own behavioural data is the marketing plan rather than a report read afterwards, so it suits a retailer whose customers browse, buy and lapse often enough for a trigger to have something to fire on. That framing is also the bill: the profile is the unit of both the product and the price, which means a list that grows faster than it converts costs more without earning more, and pruning dormant contacts becomes a recurring chore that nobody budgets for. A team that sends a newsletter on a schedule is paying for machinery it will never start, and would do better with a plain broadcast tool. Anyone weighing it against a lighter platform should also count the migration in, because the value only appears once enough history has accumulated to segment on.
