Gmailify brings Gmail spam protection and more to Yahoo, Outlook email

Google has been letting Yahoo, Hotmail, and Outlook email users plug their accounts into Gmail for about a year now, but it's been without the benefit of arguably the service's most appealing feature: superb spam protection. That changes today with Gmailify, which again lets you link your account to Gmail (without changing the actual address), but this time includes the spam protection as well as Gmail's inbox organization scheme and Google Now cards.

To get started, simply open the Gmail app, sign in to your non-Gmail account, and enable Gmailify. Should you change your mind, you can unlink you account whenever you like.

If you have an email account that isn't with Yahoo, Hotmail, or Outlook but want to take advantage of this service, Google says it will be adding other providers at some point in the future.
