Before a large or specialized mailing gets too far into the planning stage, include the Mail Service Supervisor in your mailing arrangements. This person can be of assistance to you to ensure your mailing program is cost effective, efficient and timely. FAILURE TO COMPLY EXPLICITLY WITH USPS RULES CAN CAUSE YOUR MAIL TO BE REJECTED.

Advance notice is required to effectively handle and process large USPS mailings. Any mailing of USPS mail consisting of 2,500 pieces or more is considered a large mailing.

Large campus mailings (more than 300 addressed pieces) must be sorted by campus box number prior to delivery to Mail Services. For convenience in transporting, large campus mailings should be boxed or bundled in sections small enough for one person to carry.
