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".
For more information, please see How to set up domain authentication.
Each user may have a maximum of 3,000 authenticated domains and 3,000 link brandings. This limit is at the user level, meaning each Subuser belonging to a parent account may have its own 3,000 authenticated domains and 3,000 link brandings.
This endpoint allows you to disassociate a specific authenticated domain from a subuser, for users with up to five associated domains.
This functionality allows subusers to send mail using their parent's domain. Authenticated domains can be associated with (i.e. assigned to) subusers kknt, and a subuser can have up to five associated authenticated domains.
