What is Klaviyo?
Klaviyo is the leading email and SMS marketing platform for e-commerce, powering 143,000+ brands including Glossier, Chubbies, and Living Proof. Purpose-built for online stores, Klaviyo integrates deeply with Shopify, WooCommerce, BigCommerce, and Magento to turn customer data into personalized, revenue-driving campaigns. Unlike general email platforms (Mailchimp, Brevo), Klaviyo is specifically designed around e-commerce workflows: abandoned cart recovery, browse abandonment, post-purchase sequences, win-back campaigns, and product recommendation emails. The platform ingests real-time purchase data, browsing behavior, and customer lifetime value to power hyper-targeted segmentation. Klaviyo's predictive analytics use machine learning to forecast expected next order date, predicted lifetime value, and churn risk - letting you intervene before customers leave. The built-in A/B testing, dynamic content blocks, and SMS marketing (in 15+ countries) round out the platform. Pricing is based on contacts: free for up to 250 contacts (500 email sends/month), then $20+/month scaling with list size. While more expensive than Mailchimp at scale, Klaviyo's e-commerce focus typically generates higher ROI through better targeting and automation.

Klaviyo's flow builder is where the real money is. Pre-built flow templates include Welcome Series, Abandoned Cart, Post-Purchase, Browse Abandonment, Winback, Price Drop, and Back in Stock. Our test merchants averaged $3-8 per recipient per month from automated flows alone.
