Over the summer, the process of sending a fax changed slightly. When sending a fax, you must now type +1, then the destination number followed by @fax.tc. Example: send a fax to +firstname.lastname@example.org where 717 is the area code, and 3613333 is the fax number.
To fax both a message body and an attachment, enter /b at the end of the subject line of the message.
You will receive a confirmation email after the fax server successfully sends the fax. In the event of an error, you will receive a message detailing the error.
