Advanced Email Domain Restriction

الأسئلة المتكررّة

How do I restrict WordPress registration to a specific domain?

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.

Can I block specific email providers like Gmail, Yahoo, or Outlook?

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.

Can I allow an entire top-level domain (TLD), like all .edu or .gov addresses?

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.

Can I allow only one specific email address instead of a whole domain?

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.

Does wildcard subdomain matching work?

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

Does this plugin support WooCommerce customer registration?

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.

Does this work with LearnDash?

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.

Is BuddyPress or BuddyBoss registration supported?

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

Does this work with MemberPress or Paid Memberships Pro?

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

Which contact and form plugins are supported?

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.

Does this work on WordPress Multisite?

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

How do I customize the error message shown to blocked users?

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

Can I bulk import or export my list of allowed domains?

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.

Will this affect users who already have an account?

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.

Does this plugin help stop spam or fake registrations?

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.

What happens if I don’t add any rules?

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

Does this plugin collect or share any personal data?

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.

Will this plugin slow down my website?

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.
