Everyone loves Gmail. But not everyone loves email, or the digital era. What ever happened to stamps, filing cabinets, and the mailman? Well, people asked for it, and it’s here. Google is bringing it back.

Now in Gmail, you can request a physical copy of any message with the click of a button, and it will be send to you in the mail.

Google will print all messages instantly and prepare them for delivery. Allow 2-4 business days for a parcel to arrive via post.

A stack of Gmail Paper arrives in a box at your doorstep, and it’s yours to keep forever. You can read it, sort it, search it, touch it. Or even move it to the trash—the real trash. (Recycling is encouraged.)

Google takes privacy very seriously. But once your email is physically in your hands, it's as secure as you want to make it.
COMMON QUESTIONS:

Is it free?

Yes. The cost of postage is offset with the help of relevant, targeted, unobtrusive advertisements, which will appear on the back of your Gmail Paper prints in red, bold, 36 pt Helvetica. No pop-ups, no flashy animations—these are physically impossible in the paper medium.

How about attachments?

All part of the deal. Photo attachments are printed on high-quality, glossy photo paper, and secured to your Gmail Paper with a paper clip. MP3 and WAV files will not be printed.

Is there a limit?

You can print one, one thousand, or one hundred thousand of your emails. It’s whatever seems reasonable to you.

Sorry. but this post is a joke...............he he he...... it is Gmail's April Fool's Day joke
