Abstract
A reusable mailing envelope includes a plurality of panels which, in combination, define a pocket for receipt of internal content material. One of the panels includes a window adapted to receive printed information to facilitate routing of the mailing envelope during the initial mail delivery. The reusable envelope also includes a means for preventing the readability of the printed information on the window during a subsequent mail delivery such that the routing instructions associated with the initial mail delivery are not interpreted and executed by the automated scanning equipment during the subsequent mail delivery.
