Payment Failed Recovery Abakira

When a buyer’s payment fails at checkout, they get one email a few minutes later, in their language, with a link back to their checkout.

Only failed payments. The email goes to buyers who tried to pay and could not, not to everyone who left a cart.
No discount, no marketing. It says the payment did not go through and offers a way to finish the order, with any payment method.
Silent when the order goes through. If the buyer pays another way first, no email is sent.
You see what it brought back: failed payments, emails sent, and orders placed after the email.

Install it from the Shopify App Store, then open it from Apps in your Shopify admin.
