This is really some good news, huh! You can now access Gmail without having to own a Gmail account. Google has announced that starting today it will allow users to log in with their Yahoo Mail or Hotmail/Outlook.com accounts.
Google is calling this service Gmailify and what it does is link your existing account to Gmail so that you get all the bells and whistles—spam protection, inbox organization and even Google Now cards based on your mail without having to leave your current address behind.
You can link your Yahoo! Mail, Hotmail, or Outlook.com email address to your existing Gmail address, or create a brand-new Gmail address and link to this new address. When you sign in to the linked Gmail address, you’ll see your messages from the other email provider in your mailbox.
How do you enable this feature? Just open the Gmail app, sign in to your email account(s), and enable Gmailify. And of course, you’re always in control so if you ever change your mind, you can unlink your account(s) at any time, and continue to access them through the Gmail app without using Gmailify.
