As a reminder, Every Door Direct Mail™ (EDDM) mailers and mail service providers (MSPs) can ship EDDM mailpieces to destinating offices or facilities without having to travel to those locations to drop off mailings in person. Procedures differ for EDDM and EDDM Retail. Only EDDM customers entering mail through the Business Mail Entry Units (BMEUs) may use Priority Mail Open and Distribute (PMOD) service.
