I don't much like #WebMail, and I like #Google even less, but I gotta say that #Gmail's new Subscription manager is a game-changer.

Gmail is no longer my primary email provider (thankfully), and I'm more than happy to pay out of my own pocket for email hosted by a reputable company, but I still have work email and my personal "junk drawer" email accounts hosted by the "don't be evil, lol" company. ;)
