I've been using FastMail for years, and I've looked into Rackspace Email recently, and back when it was Webmail.us. FastMail's interface is definitely superior, and their beta interface[1] is on par with Gmail. If you're using a desktop client with IMAP, then the decision matters less, but definitely take the time to check out FastMail Beta. [1] http://beta.fastmail.fm http://beta.fastmail.fm
