What’s a ConfirMailer?

ConfirMailers boxes are specially designed to conform to DMM 503.9.0 and 503.10.0. They are USPS approved parcels to use Signature Confirmation and USPS Tracking services with First-Class Mail®. These boxes are made of lightweight corrugated materials with special rigid design construction (patent pending).

How Does It Work?

This service lets mailers enjoy an “ounce rate” and still get confirmation services. Ground based carriers charge by the pound regardless of weight. This makes a savings of over $3.00 vs. traditional ground based delivery services. Savings may be even greater since USPS does not impose residential or Saturday delivery surcharges.
