A one piece mailer for use in laser printers or xerographic copying machines includes a standard size sheet which may be employed in laser printers or xerographic machines without special handling equipment and involves printing on one side only of the mailer. In addition, stable adhesive material is employed for sealing the one piece mailer which will not run or contaminate the office machines, when it is subject to several hundred degrees heat. This adhesive is preferably a water-activated adhesive other than natural gum (which is heat-activated). The first embodiment of the invention includes a mailing sheet having an upper and lower half, with the upper half carrying the addresses and the message, and the lower half having windows which match the location of the addresses on the upper half of the mailer. The second embodiment of the invention involves a mailer having a first full sheet having an upper portion on which the messages are printed, and a lower portion on which the addresses are printed. On the rear side of the main sheet is a short partial sheet toward the bottom of the main sheet forming an envelope, and with a transverse strip of adhesive immediately above the envelope pocket to seal the envelope. Perforations extend across the main sheet just above the adhesive-coated strip, so that the message section may be separated from the envelope portion, and the message portion folded and placed within the envelope, and the envelope sealed.
