What if I already have G Suite?
Google Domains works with G Suite, even if you purchased them separately.
If you purchased G Suite separately from Google Domains, and completed the G Suite set up wizard, you are ready to use G Suite.
To access your G Suite account, sign in to Gmail using a username from your domain, for example, firstname.lastname@example.org, and not the gmail.com username you use to access Google Domains.
If you need to manage your G Suite services, add users, change your G Suite billing details, or other administrative tasks, sign in to the Google Admin console. Learn more
