Required permisson: Admin 

Note: Add up to 30 alternative emails to your primary email.

As a Google Workspace  administrator, you can give a user in your organization an alternate address for receiving email at no extra cost. Do this by adding an email alias to the user's account in your Google Admin console. 

Why use an alias? If bill@solarmora.com wants a sales address for posting to the company website, give him the email alias sales@solarmora.com. Mail sent to either address then appears in Bill's Gmail inbox, and he can send email using either address. 

Add an email alias for a Google Workspace user

You can add up to 30 aliases for each user.

Important: Any Gmail user (including users outside your organization) can see aliases for any Gmail user in your organization. Learn more about renaming a user or changing a user's email address.

 - Go to admin console admin.google.com

 - From the Admin console Home page, go to Users.

 - In the Users list, find the user. If you need help, see Find a user account.

 - Click the user’s name to open their account page.

 - Click User information Email aliases. 

 - Click Alias and enter an alternate user name (the part of the address that appears before the @ sign).
Note: You can't create an alias currently assigned to someone else, either as a primary address or alias.

 - (Optional) If multiple domains have been added in your Admin console, the field to the right of the @ sign is a menu listing available domains. Select a domain for the alias address.
Note: Domains added as a domain alias don't appear in this list. A domain alias applies for everyone in your account and can't be customized for a single user.

 - Click Save.

 - (Optional) To return to the user’s account page, at the top right, click the Up arrow .

Within 24 hours (and often sooner), the user will begin to receive email sent to this address.

Send mail from an alias

Creating an email alias lets the user receive email at that address. To send mail with the alias address in the From field, they need to set up a custom From address in Gmail. They must also do this to receive messages they send to their own email alias.

Share these steps with your users: Send mail from a different address or alias.

Remove a user's email alias

 - Go to admin console admin.google.com

 - From the Admin console Home page, go to Users.

 - In the Users list, find the user. If you need help, see Find a user account.

 - Click the user’s name to open their account page.

 - Click User information Email aliases. 

 - At the right of the alias you want to remove, click Remove .
    Note: An alias with no Remove option was automatically added as a domain alias. This gives all your users       an alias at this same domain. You can't remove the alias for just one user. Instead, you need to remove the      domain alias.

 - Click Save.
 - (Optional) To return to the user’s account page, at the top right, click the Up arrow .

It can take up to 24 hours for the alias to be removed.
