Google now offers you language translation within the emails itself, which means that now you dont have to move around different services when you get a email in different language than your default language. Once you receive the email you will find a link with the original language to the translated language link along with a button which says ‘View translated message’. This is part of the Gmail Labs feature called as ‘Message Translation’ which should be activated undr Gmail > Labs Tab.

Gmail Message Translation

Turn on “Message translation” from the Labs tab under Settings, and whenever you receive an email in a language other than your own, Gmail will automatically translate it into a language you can understand with just one click.
