Klaviyo is marketing automation built on commerce data: it syncs your store’s customers, orders and browsing behavior, then drives email and SMS flows — abandoned cart, win-back, post-purchase — with revenue attribution on every send. Predictive analytics estimate lifetime value and churn risk.
It suits e-commerce brands, where it has become the default. Content businesses and SaaS teams are better served by Kit, beehiiv or Customer.io — Klaviyo’s strength is inseparable from the storefront.
