Common questions

We scan your last 30 days on install and send you a single summary email with any bounces we find. After that, alerts are per-bounce as they happen.
Order ID, customer email address, and when the bounce was detected. Phone numbers and order details are fetched live from Shopify when we send your alert. Everything is deleted when you uninstall.
“How is it possible that this simple feature doesn't exist? You have to manually check the timeline of every order to ensure there was no undeliverable errors. This has happened too many times.”
