Add multiple domains or domain aliases

About domain aliases

Gives users an email address at the domain

For example, you signed up for G Suite with your-company.com (your primary domain). You own the domain other-company.com and add it as a domain alias.

✓	Each user gets an email address at both your primary domain and domain alias
✓	Everyone can send and receive email from either address.  primary address ann@your-company.com email alias ann@other-company.com
✓	All messages arrive in the user’s primary inbox.
✓	Each mailing group also gets an email address at the domain alias. For example, if you have  info@domain.com, you automatically get info@other-domain.
✓	No extra cost per user or group. Add up to 20 domain aliases to your G Suite account.

Important: A user's alias address might be visible to other users. For example, if a recipient searches Gmail for messages from "Ann", search results might include messages from ann@your-company.com and ann@other-company.com. Learn more in the FAQand Limitations with multiple domains.

If you manage a large organization: Your users might have a personal Google Account that already uses the domain. When you add the domain alias, those users' accounts are automatically renamed. All data in the accounts remains outside of your organization’s management. To find users with Google Accounts, first add the domain as a secondary domain. The list of accounts is generated within 24 hours. Learn more about conflicting accounts.

About secondary domains

Manage separate teams of users or businesses at different domains

For example, you signed up for G Suite with your-company.com (your primary domain). You manage a team that has their own domain, other-company.com. You add other-company.com as a secondary domain to your G Suite account. 

Important: Some information and features are linked only to your primary domain. For example, you can't set up a separate billing address or company logo for a secondary domain. Learn more in the FAQand Limitations with multiple domains.
