If you like all the features of Gmail but don’t want to go through the hassle of creating a whole new email address, now you can “Gmailify” your old email accounts.
To get started, you’ll need to open the Gmail app, sign in to your email account(s) and enable the Gmailify button, Google software engineer Michael Käser in the company blog post wrote. This only works in the Gmail app and will not affect your email accounts otherwise.
By Gmailifying your account, you’ll get access to Gmail’s spam protection and inbox organization (social, updates and promotions sections), search functions and notifications. Interacting with your mail, whether reading or deleting messages, will have the same effect in the original email account’s inbox.
If you want to un-Gmailify your account, you can unlink the button at any time without affecting that email address.
According to the blog post, Google is planning to add other email providers beyond Yahoo!, Hotmail and Outlook in the future.
