Google Mail Envelopes is a concept from designers Rahul Mahtani & Yofred Moik that allows people to mail their correspondence with the click of a button.

If google implemented this concept into Gmail, then you would type your letter in Gmail and then click the “send envelope” button in Gmail instead of “send” button. Then your letter is printed by Google and mailed via usps  (for a small postage fee) in an envelope which has “Google Maps” printed on it showing the sender’s and recipients destination along with the route.
