Advanced Email Domain Restriction

Go to Settings → Domain Restriction and add the domain (e.g. yourcompany.com) to the Allowed Domains list. Once saved, only email addresses ending in @yourcompany.com will be able to register — every other domain is blocked automatically.

Yes. Since AEDR works as an allow-list, simply don’t include gmail.com, yahoo.com, outlook.com, or any other webmail domain in your allowed list, and registrations from those domains will be blocked. This is a common way to reduce spam and fake account signups.

Yes. Add a rule starting with a dot, such as .edu or .gov, and any email address ending in that TLD will be allowed, regardless of the domain in front of it.

Yes. Add the full address (e.g. john@example.com) as a rule, and only that exact email will be allowed to register — useful for granting a single exception.

Yes. A rule like *.example.com allows both example.com itself and any subdomain such as team.example.com or sales.example.com.

Yes. AEDR hooks directly into WooCommerce’s registration process, so the same domain rules apply whether a customer registers through the standard WordPress form or through WooCommerce’s My Account / checkout registration.

Yes. AEDR validates the email domain on LearnDash’s Login & Registration modal as well as the default WordPress registration form, so students can only register with an approved email domain — useful for restricting course access to .edu or company email addresses.

Yes. AEDR validates the email domain during BuddyPress and BuddyBoss community signup, in addition to standard WordPress registration.

Yes. Both MemberPress signup and Paid Memberships Pro registration/checkout are validated against your allowed domains list.

AEDR automatically validates email fields in Contact Form 7, WPForms, Elementor Pro forms, Gravity Forms, and Fluent Forms, using the same allow-list you configure once in Settings → Domain Restriction.

Yes. AEDR validates email domains during multisite user signup as well as single-site registration.

You can customize the error message shown for restricted domains in the plugin settings under the “Custom Messages” section.

Yes. Use the CSV Bulk Upload feature to import a large list of rules at once, and the Export to CSV feature to download your current list for backup or review.

No. AEDR only validates email domains at the point of new registration. Existing user accounts are never affected, logged out, or deleted, even if their email domain is later removed from the allowed list.

Yes. Because only email domains you explicitly trust can complete registration, AEDR is commonly used to block spam bots, disposable/throwaway email signups, and fake accounts that target open registration forms.

If no domains are configured, AEDR does not restrict registration — all email addresses are allowed, exactly as with a default WordPress install.

No. AEDR does not collect, store, or transmit any personal data to third parties. It only reads the email address submitted during registration to check it against the domain rules you configure yourself.

No. AEDR is lightweight, performs a single fast comparison against your configured rules at the moment of registration, and adds no measurable overhead to page load or checkout speed.
