Princeton Gmail: How to use multiple accounts simultaneously (or not)
I now have two (three... four...) Google accounts. One is Princeton Gmail and the others are personal email addresses. What are my options?

Decide if you want to have one email address, or two (or three... four...) and then continue. Some people like to receive all their mail in one Inbox, and some people like to keep their mail separate, for whatever reason. At this time, Google does not offer a truly satisfactory method to merge accounts, but you do have some options for using several Google accounts at once. Read on.

Remove your current forwarding of your Princeton email
Your email is being delivered to If you remove the current forwarding of your Princeton mail using OIT's Email Forwarding Tool, you will in effect have two netIDs at Google; one Princeton and one personal. See how to use them simultaneously below.

Continue forwarding your Princeton mail to your private account
If you would rather get all your email in one account and you prefer your address, use OIT's Email Forwarding Tool. Please make sure you are forwarding your mail correctly, and note that OIT does prefer forwarding from Princeton rather than "popping" from Gmail. See more below on how to change your return email address if you would rather send mail from but receive in

Princeton Gmail is free of paid advertising and includes enhanced security and privacy. Princeton Gmail also includes a 25GB mailbox quota and access to the Princeton directory. Just sayin'.

The technical stuff
  • You can sign in to multiple Google accounts in the same browser session, but not all Google products may be available to you because of the way Google uses cookies. See Google's instructions on how to use multiple sign-in for more than one Google accounts. You can access up to ten accounts in one browser window in one session. Remember not all products support multiple sign-in, so for certain products you will need to use one of the next bullet options below. The first account used to sign in is your default for that session.

At any point you can see which account you are signed in as (and whether you can add or switch to a different account), by clicking on your email in the upper right corner of the screen.

  • Forward all your email from secondary email addresses to the one primary Google address that you prefer. Using your Princeton Gmail account offers more space than a personal Gmail account, and also allows you the use of the Princeton address book when composing email messages; and it is advertising free. Google's help pages have instructions on how to use different sending addresses within the same account.
  • Use different browsers for each of your accounts (Google Chrome, Firefox, and Safari for example).
  • Use Google Chrome's incognito window or the incognito/private browsing modes on your browser of choice to sign in to your second account. Note: your history and login information won't be saved while using this option.
