How Registration Email Blocker works
Show full descriptionShow less
Registration Email Blocker decides which email domains are acceptable on your site. Run it as a blocklist to refuse the providers you name, or as an allowlist to accept only the ones you approve.
The check is applied everywhere an address can be set, not only on the registration form:
the WordPress registration form
the profile screen and “Add New User” in wp-admin
the WordPress REST API
WooCommerce registration
the WooCommerce checkout, both the classic shortcode and the newer block based checkout
the “Account details” page of the WooCommerce My Account area
Checking email changes matters as much as checking registration. If only the registration form is guarded, an account can be created with an accepted address and switched to any other one a minute later. That option is on by default and can be turned off.
What it does
Two modes. Blocklist refuses the domains you list; allowlist accepts only the domains you list. Subdomains are matched in both directions, so listing example.com also covers mail.example.com.
Two levels of strictness. Refuse the address outright, or allow it and record the attempt.
Internationalized domains. Names such as почта.рф are converted to their punycode form when saved, so they match real addresses. Entries that are not valid domain names are reported back to you rather than silently dropped.
Administrators are exempt by default, so a mistake in a domain list cannot lock you out of your own site.
