I&#x27;ve started using more of Gmail&#x27;s features to help control this.<p>First, there is the actual email address itself: Gmail ignores periods and anything after a + (plus sign). So every new site I sign up for gets a different email address, usually my normal email plus a postfix named after that particular site. This way, when I get emails from recruiters saying they found me through LinkedIn, but are actually using a form of my email address I&#x27;ve only used on Github, I know immediately what is going on.<p>And second, I just mark them as spam. Because they are.
