Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartback brings back shoppers who left before paying, using two channels in one sequence: a reminder email and an optional browser notification. Instead of a fixed delay, send times come from your store's own buying pattern — first from your catalog, then from what actually recovers carts for you. You control who may be contacted, whether to add a discount, and how the emails look.
Failed payments happen when a customer's card is declined or an error interrupts checkout. Most of these sales are lost. RevivePay watches your store for failed payments and automatically emails the affected customer a link to resume their checkout. You control the email schedule, and every recovered order is tracked so you can see exactly how much revenue came back.
