Klaviyo

Klaviyo is the email and SMS marketing platform built from the ground up for e-commerce, providing the deepest native integrations with Shopify, WooCommerce, BigCommerce, and other major e-commerce platforms available. While general-purpose email marketing tools can connect to stores via plugins, Klaviyo's e-commerce DNA means every feature — from segmentation to automation to analytics — is designed around the specific data and workflows that online retailers need.

Native e-commerce integrations go far beyond simple contact syncing. Klaviyo pulls real-time data on browse behavior, purchase history, cart contents, product interactions, and customer lifetime value directly from your store. This data powers segmentation that no general-purpose email tool can match: target customers who browsed a specific product category in the last 7 days, purchased more than 3 times in the past year, or have a predicted next order date within 2 weeks.

Pre-built automation flows address the most profitable e-commerce email scenarios: abandoned cart recovery, welcome series, post-purchase follow-up, win-back campaigns, cross-sell recommendations, and browse abandonment. These flows come pre-built with best-practice configurations and typically generate measurable revenue within days of activation.

Predictive analytics use machine learning to calculate customer lifetime value, predict churn risk, estimate next order date, and identify customers most likely to become VIP purchasers. This predictive intelligence helps merchants focus retention efforts and marketing spend on the customers most likely to deliver long-term value.

SMS marketing is integrated alongside email, allowing merchants to build coordinated multi-channel campaigns. Abandoned cart SMS messages, flash sale announcements, and delivery notifications supplement email campaigns with the immediacy that SMS provides.

The free plan supports up to 250 contacts and 500 email sends per month. Paid pricing starts at 20 USD per month and scales based on contact list size, with no feature gates — all capabilities are available at every paid tier. This pricing model is attractive but can become expensive as contact lists grow beyond tens of thousands.
