Outgoing Fax : We define this to be any letter sent out via the US Postal Service as requested through our API. The following method calls have faxing associated with them:

• LetterCreate()
• LetterForward()

The high cost is due to postage, materials (paper, envelope, toner), and labor (folding, stuffing, delivery). We've made our API robust enough, though, to turn off this feature if you so choose.
