Folded Self-Mailer Regulation Changes Set for January 5, 2012

In collaboration with the mailing industry, the Postal Service initiated a mail piece design study to revise Folded Self-Mailer (FSM) standards for automation letter-size formats. As a result of the study, the mailing standards were revised to allow more creative design options that better match mail processing capabilities. For the MLOCR industry, you must inspect your client’s products prior to running on equipment to ensure the mail piece conforms to the new standards.
