Add domains to your Google Workspace account
If you own another domain, you can add it to your Google Workspace or Cloud Identity account. For example, you might manage multiple businesses or brands, each with their own domain. Depending on your needs, you add a domain as a user alias domain or a secondary domain.
If you try to add a domain that includes "gmail" in its name, it won’t be accepted. For example, if you try to add a domain such as xxgmailxx.com, you’ll get an error.
