Use this brilliant hack to filter out spam and promotions: Since newsletters are legally required to have an unsubscribe option somewhere, that gives them a unifying word that you can filter out!1. Go to your filters (click the gear, click settings, then click filters). Scroll to the bottom and click "Create a new filter." 2. Under "Has the words," write "Unsubscribe," then hit "Create filter with this search."3. Mark "Skip the inbox (Archive it)."4. Mark "Apply the label" and create a label called "read/review" or something similar. This way, you can glance at anything that's automated all at once when you go to your read/review label, rather than having it bother you in your inbox. If you want to continue receiving some of these emails in your inbox (say, notifications from Facebook and Twitter), you can just edit the filter to create exceptions for those words (i.e., put "Facebook" "Twitter" under the "Doesn't have" field). Bonus info: There's often a handy "Unsubscribe" link right next to the sender's name on promotional emails! 10. Make the most out of your tabs! Gmail's new tabs can be a bit confusing at first, but they're well worth taking the time to get used to. To enable them, just click on the gear and click "Configure Inbox," then select the ones you want to use. Promotions and Updates are great ways to keep your endless updates from Facebook, Twitter, and elsewhere in a manageable place that you can bulk-delete at a glance, but the secret best one is "Forums," which will seperate out anything that's sent to a group so that you can prioritize emails from people who put your name in the "To" line and look at group threads when you're ready to move on from your main inbox. 11. Enable the Inbox Count in your browser tab: This is another useful labs feature (gear icon > settings > labs > search for "unread message icon" > enable > save changes) that will let you see how many new messages you have by having a quick glance at the gmail browser tab rather than having to click over.
