How to Clean out Your Gmail Inbox

Have you opened your Gmail inbox, only to discover that you have gradually accumulated hundreds or even thousands of emails? Did it seem like a difficult choice: delete all your old messages and lose the record of all your important emails, or archive them all and keep a bunch of junk you never read for good reason? Luckily, Gmail has some simple but powerful tools to help you search and manage huge numbers of emails.

Method 1 of 5: Clean All Read Mail

2

Next, click in the Gmail search box. Type in:inbox is:read (without quotes) Then, click the blue Search Mail button. You will now see a few of the most recent emails you have actually read.

3

Find the checkbox button for selecting messages at the top left of the results. Click it. A drop down box will appear that has the options, "Select: All, None, Read, Unread, Starred, Un-starred". Click on "All" to select all the emails that match your search. All the emails on the page will be checked and highlighted.

4

Click the link at the top of the list that says, "Select all conversations that match this search." This will make sure you have selected even the messages that don't fit on the first page of results.

5

Click the "Archive" button at the top of the email area. Now all of your read emails have been saved to your archive, where they can be searched but where they won't clutter up your inbox.
