Configure a custom email domain

A custom email domain allows you to present a branded experience to your end users. Email that Okta sends to your end users appears to come from your custom email domain instead of noreply@okta.com. You can switch to a different custom domain or revert to the default Okta domain, but you can use only one email domain at a time.

Okta sends your super admins a confirmation email after your custom domain is configured and operating correctly. To ensure continuous operation, Okta polls your custom email domain once every 24 hours. If a problem occurs, Okta alerts super admins by email, and Okta-generated emails are sent from the default domain noreply@okta.com until the problem is resolved.
