3602's U.S.P.S. PROOF OF MAILING - An official from the United States Post Office holds a physical office in our Production Facility. He is responsible to validate the shipment of every envelope leaving the Valpak Production facility. This official validates that each NTA has 10,000 envelopes being mailed out from the facility to the DDU destination tagged to the NTA. A DDU, Direct Delivery Unit is your local Post Office.
The shipment of our Envelopes from FL to NH takes approximately 48 hours. They leave our shipping docks and are trucked directly to each SCF who handles the zip codes under any one NTA. The SCF, one distribution level above the DDU's receives our mail directly. As the Valpak Envelope are Bar-Coded, unlike any other Direct Mail Promotional piece in America, it is able to be processed through their electronic machines thus allowing our envelopes to be mixed in directly with every other piece of 1st class mail the consumers receive. ALL promotional mail you receive is 3rd Class bulk so if it is not bar coded like Valpak's envelopes, which it is not, the Post Office has no responsibility when it falls off the crates, pallets or simply goes missing. One more reason why Valpak is the Right Choice For Your Business!
This link below will provide you with the certification, Proof of Mailing (3602) that the U.S.P.S. provides to Valpak for our most recent mailing.
