First Class Mailing Boxes
ConfirMailer are designed to take advantage of the USPS Signature & Delivery Confirmation with First-Class Mail program

Effective July 1, 2002, the U.S. Postal Service expanded its highly popular Delivery Confirmation and Signature Confirmation services to include First-Class Mail parcels. Converting from traditional options for tracking and confirmation to this new First-Class Mail service, results in huge savings for both the retail and commercial uses.
