Fewer rejected mailings
Sortation and containers that match USPS rules get through acceptance the first time.
Compliance
Presort discounts only pay off if the mailing is accepted. MaxPresort OS is certified to produce sortation and documentation USPS trusts.
PAVE™ Gold
The Presort Accuracy and Validation Evaluation (PAVE™) program is how USPS tests presort software. Vendors run USPS-supplied test files, and the output (sortation, container assignment, labels and documentation) is checked against postal rules.
Gold is the highest level. MaxPresort OS holds it, which means its presort logic and reports have been validated by USPS itself. You can confirm it on the USPS PAVE™ Certified Products List.
