Gmail just offered me to import my mails from my Yahoo account!
I have seen this alert on the Inbox dashboard for the first time ever.
I am not sure if this is a new thing from Google.
I do not remember adding my Yahoo account details to my Google account in the recent times. So, this looks like something Google has just started to push to the users of Gmail!
I should mention here that Microsoft recently posted a long blog post on why you should consider switching from Gmail to Hotmail!
