About domain aliases

Give users email addresses at both domains

For example, you signed up for Google Workspace 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.

Ann's address ann@your-company.com
Ann's 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@your-company.com, you automatically get info@other-company.com.
No extra cost per user or group. Add up to 20 domain aliases to your Google Workspace account.

Note: 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.

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 accounts, first add the domain as a secondary domain. The list of accounts is generated within 24 hours.
