A return mailer bearing computer readable information including a mailing panel of a first surface porosity, adapted to bear an address of a returnee, further including a folding sealing flap along one transverse edge that is adapted to form a transverse edge of the envelope when it is folded and sealed. Also included is an information panel of a second surface porosity, bearing machine readable information on at least one side, which includes two transverse perforations, wherein the perforations are separated by a longitudinal distance sufficient to span the portions of each side of the information panel bearing information of interest to the returnee. The two panels are joined by an adhesive along the two longitudinal segments of their periphery to form the two longitudinal edges of the envelope. The adhesive maintains the mailer in sealed condition during mailing, while not contributing to gnarling or tearing of either panel upon separating the two panels upon opening. The two panels are bonded along the transverse segment of their periphery distal to the sealing flap to form a transverse edge of the envelope. The panels remain bonded along this transverse edge upon tearing the information panel along both of the perforations.
