Your mailing department already knows that new mail sorting machines for catalogs will require new schemes for preparing your catalog for mailing. They probably haven't told you that new addressing requirements on catalogs will change the real estate of your catalog's front or back cover. Don't let your creative team be caught flat footed. Understand what the address changes will be, what the Postal Service expects, when it expects it, and how your catalog covers can be ready for the change. Don't leave this up to your mail preparation team.
