Keep work and personal accounts separate
A Google account lets you register several accounts at once without ever signing out, and switch between them with a single click. This is especially useful if you want to keep work email and personal email cleanly separated instead of mixing them in one inbox.
Browser profiles offer an even stronger separation
If account-switching within Gmail itself still feels like it mixes things together too much, most browsers also support separate "profiles" β essentially a completely separate browser identity with its own bookmarks, extensions, and signed-in accounts. Setting up one browser profile for work and another for personal use keeps everything, not just Gmail, cleanly separated at the browser level.
Frequently Asked Questions
How many accounts can I add?
The official limit is generous enough that it rarely comes up in everyday use, so most people never need to think about hitting a cap.
Do I get notified about new mail on accounts I'm not currently viewing?
If you have browser notifications turned on, you can still get notified about new mail arriving in an account you're not actively looking at.
