Today we share a very interesting email to fax service that is absolutely free, you can send an unlimited number of faxes and best of all, the service covers most cities in the world.

Called TMC, this Internet fax service allows you write a FAX message either in a based web form or you can send an email message to a special address that contains the fax machine number of the recipient as well as the coverpage text.

For instance, if you like to congratulate Sergey Brin on his marriage with Anne Wojcicki, send an email to the following address:

remote-printer.Sergey_Brin/Google_Inc@16502530001.iddd.tpc.int

[Google fax machine number: 650-253-0001]

The cover page of the fax will say:

Please deliver this facsimile to:
