With Gmailify, users will be able to link their existing account to Gmail and get access to:
- Spam protection
- Inbox organization
- Google Now cards based on their mail
- Open the Gmail app on your Android phone or tablet
- In the top-left, touch the Menu button
- Scroll down and tap Settings
- Tap the non-Gmail account you’d like to link
- Tap Link account
- Done !!
the Gmailify feature is now rolling out on the Gmail app for Android devices and only supports Yahoo! Mail and Hotmail/Outlook for now, with more email providers to be added later on.
