Give a user an additional “email alias” address (sales@)

As a G Suite admin, you can give a user an alternate address for receiving mail, in addition to a user’s primary address. Do this by adding an email alias to their account, in your Google Admin console.Example: If bill@solarmora.com wants a sales address for corresponding with customers, give him the email alias sales@solarmora.com. Mail sent to either address then appears in his Gmail inbox, and he can send email using either address. 

Give users email aliases at no extra cost.

Important: Aliases are not private, and in some cases they’re visible to other users. For example, if a recipient searches Gmail for messages from bill@solarmora.com, search results might also include messages from his alias, sales@solarmora.com.

If your organization’s account doesn’t yet have this update, your interface will appear slightly different.

Add an email alias for a G Suite user

You can add up to 30 aliases for each user, at no extra cost.

Tip (If available): Try the quick link. At the top of your Admin console Home page, click Create an alternate email address, search for the user, click Proceed, and then go to step 5 below.

  1. In your Google Admin console (at admin.google.com)…
  2. Go to Users.
  3. In the Users list, find the user. If you need help, see Find a user account.
  4. Click the user’s name to open their account page.
  5. Click User information and then Alternate email addresses (email aliases)
  6. Click Alternate email and enter an alternate username (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.
  7. (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.
  8. Click Save.
  9. (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 email 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

  1. In your Google Admin console (at admin.google.com)…
  2. Go to Users.
  3. In the Users list, find the user. If you need help, see Find a user account.
  4. Click the user’s name to open their account page.
  5. Click User information and then Alternative email addresses (email alias)
  6. At the right of the alias you want to remove, click Remove Cancel.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.
  7. Click Save.
  8. (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.

Used only for email

People can use email aliases only to send and receive mail. They must keep using their primary address to sign in to their account, sync with a mobile device, or share Google Docs and Sites.
