NAC was originally founded as Metro Envelope out of Harlem, New York in 1934. Over the course of the following years, the small operation expanded as one envelope converter was replaced by twelve. By 1965, those twelve converters had gained twelve counterparts to better serve the customer base in the thriving direct mail industry. As of 1978, the transition from envelope production to direct mail manufacturing was complete. Metro Envelope pushed westward to Duncansville, Pennsylvania and into a facility three times its previous size. Here the company became NAC.
Throughout the next four decades, NAC continued to add to its integrated marketing platform with acquisitions and capabilities enhancements that touch all aspects of the direct marketing value chain: creative services, data services, print production, and literature/product fulfillment.
