Electronic Computer Originated Mail

Overview
Electronic Computer Originated Mail (E-COM) was a U.S. Postal Service service directed to large volume mailers who would pay a 1978 estimated rate of $.30 to .55 per message for the first page depending on total monthly volume.

"As E-COM was originally proposed, the Service would accept customers' nonhardcopy messages (stored on magnetic tape or disc or transmitted directly to the Service's computer equipment) and electronically transmit these messages via communication carrier's lines to any or all of 25 serving post offices. Once received at the postal facility, the message would be printed, enveloped, and placed in the normal mail stream for delivery within 2 business days."
