Want to get rid of those newsletters for good? There's an "unsubscribe" button next to the sender's address in promotional emails. It's a great one-click solution for decluttering your inbox!
Another tip for the newsletters that don't get the "unsubscribe" button: type "unsubscribe" into the search box, and you'll probably find every deal, discount, and event email notification you've ever signed up for. You can also select all (but make sure to click "select all conversations that match this search" too) to banish historic newsletters from your inbox for good
