In a USPS Marketing Mail automation mailing, what is the minimum number of pieces needed for 5-digit sacks/trays with dimensions 6" x 11" x 1/8"?

In the context of USPS Marketing Mail automation, when preparing mail for 5-digit sacks or trays, the minimum number of pieces required is determined by the specific guidelines set forth by USPS. For 5-digit sacks/trays, the threshold is typically set at 150 pieces. This number is significant because it reflects the volume necessary to qualify for automation rates, which offer discounts and efficiencies for bulk mailings.

This requirement incentivizes businesses to consolidate their mailings and streamline the processing through the USPS, allowing for better handling and faster delivery timing. Thus, when planning a mailing that utilizes 5-digit sacks or trays, knowing that a minimum of 150 pieces is needed is essential for meeting USPS criteria and maximizing the benefits of automation discounts.
