An authenticated domain allows you to remove the “via” or “sent on behalf of” message that your recipients see when they read your emails. Authenticating a domain allows you to replace sendgrid.net with your personal sending domain. You will be required to create a subdomain so that SendGrid can generate the DNS records which you must give to your host provider. If you choose to use Automated Security, SendGrid will provide you with 3 CNAME records. If you turn Automated Security off, you will get 2 TXT records and 1 MX record.
Domain Authentication was formerly called "Domain Whitelabel".

This endpoint allows you to disassociate a specific authenticated domain from a subuser.
Authenticated domains can be associated with (i.e. assigned to) subusers from a parent account. This functionality allows subusers to send mail using their parent's domain authentication. To associate a authenticated domain with a subuser, the parent account must first authenticate and validate the domain. The the parent may then associate the authenticated domain via the subuser management tools.
