TTBlacklist ‑ Order Guard

This app helps Shopify merchants manage an email blacklist and block unwanted orders efficiently. It enables easy blacklist management—you can manually add emails, bulk import via CSV, and view/delete entries directly in the Shopify Admin. Before checkout, the app automatically checks if the user’s email matches the blacklist. If a match is found, it stops the order submission process and shows a clear notification to the user.
