A shipping envelope comprising first, second and third panels, each having a front and a back, are adjoined side to side adjacent a first fold line between the first and second panels, and a second fold line between the second and third panels. The first panel has fixed information including a return address on the front and a first adhesive on the back to secure the first panel to a shipping container. The second and third panels include one or more areas for printing a delivery address and other variable information. A second adhesive secures the first panel to another panel when the panels are folded along the first and second fold lines so that they overlie the first panel, so that the delivery address is facing out on the envelope. Advantageously, the second and third panels comprise a first ply and the first panel comprises a second ply with the first and second plies overlying one another and secured together by a third adhesive therebetween adjacent the first fold line.
