Spam filters are the first line of defense in keeping your inbox free from unwanted emails, but they can’t too all the heavy lifting. Since most unwanted emails come from promotional sources (like coupon deals, hotel discounts, social media notifications and sales from places you’ve shopped online) the easiest way to reduce the email madness is to click the “unsubscribe” button underneath the emails you don’t want. All commercial emails have to include this opting-out option, and its a quick way to reduce the junk you’ll receive in the future.
