I use two Gmail accounts: one is my personal account and the other I share with my family (we use it to subscribe to groups like my children’s classroom mailing list). Checking these two different accounts used to mean I had to sign out and back in to Gmail all the time. Not anymore.
Yes, Gmail now supports full email delegation. By way of a new feature in settings, you can grant another Google account holder access to your email account. This allows another person to both send and receive emails on behalf of your account.
This feature has been available for some time for Google Apps accounts. But sometimes regular people have assistants too — or simply email addresses that they’d like multiple people to manage in a more coherent way. For example, when a message is sent from the account with access to yours, it appear as being from your address, but with include “sent by XXXX@gmail.com”. Nifty.
To grant access to another account, click the Settings link in the top right corner of Gmail. On the “Accounts” tab, you’ll see a new section where you can “Grant access to your account.”
The account you add will get a verification email with links to accept or deny access. Once the account accepts, a small down arrow will appear beside the email address at the top right corner of Gmail which can be used to toggle between accounts.
Each account will open in a different browser tab or window so you can view both accounts simultaneously, all while signed into your primary account. When you send a message from email@example.com while signed in as firstname.lastname@example.org, it will appear as being sent by email@example.com on behalf of firstname.lastname@example.org.
Signing out of any one of the accounts will sign you out of all the accounts you’re currently viewing, and, of course, you can revoke access at any time.
