Now, You can use the Gmail’s feature with other email accounts
After allowing users to use their Outlook and Yahoo mail accounts in Gmail App, now Google allows users to use Gmail features such us Spam Protection or Now Cards with non-Gmail accounts.
The all you need is an either OutLook or Yahoo mail account. After signing to Gmail with these accounts, you will be able to use your OutLook or Yahoo as if it is a Gmail Account. Spam Protection and Now Cards are the features that are available. While Spam protection obviously protects you from Spams, Now Cards organizes your mails in different cattegories such us Travel.
