第9章 Email domain configuration

Emails sent from the 3scale system to developers on your behalf are distributed by SendGrid. The configurations guidelines in this section allow the emails to come from one of your domains rather than from 3scale.

This feature is not available on Personal plan accounts.

After you have the email setup configured on your side, open a support case on the Red Hat Customer Portal to complete the process. Just as for SSL certificates, we recommend you complete these steps as soon as possible.
