See every featureCartSync saves every logged-in customer's cart and restores it on any device — automatically. Set merge or replace mode, sync in the background on every cart change, and send automated emails for price drops, back-in-stock alerts, and idle carts. Connects to Klaviyo or your own SMTP. Works with any Shopify theme, no code required. Built with official Shopify APIs.
Shoppers browse across devices, but Shopify carts don’t follow when they switch devices. Persistent Cart prevents lost sales by automatically syncing logged-in customers’ latest carts across devices in the background. No emails, pop-ups, notifications, opt-ins, or code changes — just seamless cart persistence that reduces abandonment, grows AOV, and helps shoppers keep buying instead of starting over.
