Add approved user email domains

If you are a CertCentral Administrator, you can now specify what email domains users can create an account for. This helps to prevent emails from being sent to non-approved, generic email domains (,, or domains owned by third parties.

If a user attempts to set or change a user email address to a non-approved domain, they receive an error.

Add email domains

  1. In your CertCentral account, in the left main menu, go to Settings > Preferences.

  2. Expand Advanced Settings.

  3. Under the Approved email domains section, enter the domains of email addresses that users can create an account for.

This does not affect existing users with non-approved email addresses. It only impacts new users and email changes made after configuring this setting.
