A feature that one allowed Gmail users to share access to their mail just got a lot more useful by adding support for multiple accounts. Email delegation lets you designate certain Gmail friends who can read your emails and send from your address. Now, you can assign your own multiple Gmail accounts and toggle rapidly between them without the need to log out of your primary account.
Here’s how to set it up: log in to your primary Gmail account. In the upper-right corner of the screen, click on settings. Select the “Accounts & Import” tab. In the section that says “grant access to your account,” click the “Add another account” link. Once you’ve submitted another account, log into it to click an approval link in the confirmation email. Log back into your primary account and look to your name in the upper-right corner of the screen. Click that drop-down arrow and log into another account. Once logged into your secondary account, you can toggle back and forth between the two using that same arrow. Great! No matter which account you’re viewing at a given time, you can send from your primary account.
This simplifies my email situation considerably, as I was using three different clients for three different Gmails. Now, I can stay signed in to all three with one browser window. Setting up different themes for each account seems like a good plan for staying organized.
