Collected facts
This app automatically detects and flags fake/disposable or invalid email addresses during checkout or order creation. Validation in checkout requires Shopify Plus. By identifying issues like disposable, misspelled, or suspicious emails, it helps merchants reduce failed communications, avoid fake orders, and streamline fulfillment. The app works in real time, ensuring only valid email addresses are used, helping merchants maintain accurate customer data and improve overall store performance.
