Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMost bad checkout emails are not fraud, they are mistakes. A shopper mistypes their address, the order goes through, and the confirmation and tracking never arrive. MailShield catches the typo at checkout and suggests the right domain so they can fix it. It also refuses disposable and temp-mail domains, plus any domain on your own blocklist, before the order is created.
You can set rules to prevent certain email domains and name patterns from being able to create accounts or checkout. This helps you prevent emails from getting passed to platforms like Klaviyo that may charge you extra for users. We help you decrease fake account bloat and prevent malicious, fraudulent and fake emails from creating orders so you have less to deal with later on.
