About Klaviyo
Klaviyo is purpose-built for e-commerce, with native integrations that pull real-time purchase data, browsing behavior, and customer lifetime value directly into segmentation and automation. Shopify stores particularly benefit from one-click integration and pre-built flows.
The free plan supports up to 250 contacts with full access to all features including flows, segmentation, and reporting. Klaviyo uses this data density to power abandoned cart recovery, post-purchase sequences, and win-back campaigns that outperform generic platforms.
SMS marketing, predictive analytics (next order date, churn risk, lifetime value), and AI-powered subject line optimization make Klaviyo the default choice for serious Shopify and WooCommerce merchants.
