Google launched Multiple Inboxes feature in Gmail labs recently. With Multiple Inboxes you can see different customized inboxes when you login to Gmail. With the same feature you can see your several email accounts in the same browser window. It is possible if you are forwarding all your work or school or other email to Gmail.

How to manage several email accounts with Multiple Inboxes

1. Turn on Multiple Inboxes from the Labs tab under Settings.

2. Setup a filter to auto-archive all mail sent to your work or school address.

3. Customize one of your multiple inboxes to show mail sent to your other address. To do this, go to the Multiple Inboxes tab under Settings and set up one of the panes to search for mail sent to your other address.

4. (Optional) Use a "custom from" address so that replies will be sent from Gmail but as if they’re from your other account. This way, your coworkers or classmates won’t know the difference.
