Block Temporary Email

This plugin will verify every email address submitted by users. It’ll automatically detect and block disposable, temporary email addresses. It’ll give a nice warning message when users are signing up, logging in, or changing email to a temporary email.

The plugin checks the domain name using a service named IsTempMail. If a domain name is blocked, it will be stored into a local blacklist. You can also manage your own local whitelist and blacklist to allow or disallow certain domains.

The plugin integrates with the WordPress built-in function is_email(). It works seamlessly with other plugins including WooCommerce, Contact Form 7, Gravity Form, Jetpack/Grunion contact forms, Kadence Blocks Forms as well as other formbuilders and ecommerce plugins and WordPress’ own registration form.
