WordPress Restrict Email Domains

Open registration can bring in accounts from outside the group a site serves. This plugin lets administrators decide which email addresses can be used to register, helping membership communities, educational sites, intranets, and organizations keep sign-ups within their intended audience.

Create rules for individual addresses, full domains such as example.com, or extensions such as .edu and .org. The plugin also supports regular expressions for more specific rules and lets administrators customize registration error messages. It works with WordPress Multisite, BuddyPress, WooCommerce, WP Members, Ultimate Member, and Paid Memberships Pro.

Features

• Address-based rules: Allow or restrict registration for specific email addresses, giving administrators control over who can sign up with an individual address.
• Domain restrictions: Set rules for whole email domains, such as example.com, to limit registration to people using addresses from selected organizations.
• Extension filtering: Restrict sign-ups by domain extension, including extensions such as .edu or .org, to suit communities with specific email requirements.
• Regular expression rules: Use regular expressions to define email domain rules for registration scenarios that need more precise matching.
• Custom error messages: Set the message users see when their registration email does not meet your rules, so the restriction is clear at sign-up.
• WooCommerce registration control: Apply email domain restrictions to WooCommerce customer registration, useful for stores with membership or business-to-business models.

Best for

• Membership communities with restricted sign-ups
