Like the old contents in our refrigerators, the daily deals, newsletters and special offers we receive as emails each day all eventually expire. These emails aren't spam because we signed up to receive them, but sometimes they prevent us from getting to the stuff we'd prefer to read first, or is more important to us. Hotmail considers these expired offers to be a form of “graymail” that you signed up for and even sometimes want, but can lose their relevance with time. Thankfully, they've come up with a way to get rid of them altogether to make our lives simpler.
