Abstract: An envelope assembly that is particularly suitable for return receipt requested mail (such as certified or registered mail) mounts the return receipt on a body portion of the envelope, opposite the envelope flap. The body portion and flap typically have tractor drive strips so that they can be processed by automatic printing equipment, and the return receipt is connected to the envelope in such a way that there is a minimal chance of the return receipt being "chewed up" by the printer or other handling equipment. The outgoing address is provided on the flap, and certified mail indicia may extend between the flap and the body of the envelope.
