Email experts advise against using your email inbox as storage and instead suggest frequently cleaning it out and storing old messages in archive folders instead. For Gmail users, here’s a filter that will move all messages older than a certain date to your archive. Click “Create a Filter” and in “Has the words” enter “before:2009/07/01”. Now choose “Next.” Check “Skip the Inbox” and the box that says “Also apply this to the conversations below.” Now click “Create Filter.” Of course, you can change the filter to use any date of your choice, in the format “before:YYYY/MM/DD”.
