Envelope Vendors Seek Piece of Postal ‘Summer Sale’ Pie

Envelope suppliers Western States Envelope & Label and Worcester Envelope have been aggressively peddling their services not just to help mailers reach volume minimums to qualify for summer sale discounts. “The stimulation of letters by the USPS summer sale has a sustainability advantage,” said Brook Spaulding, principal and chief technology officer of 7R Communications in a statement. 7R licenses a suite of USPS-approved mail pieces designed to boost sales while reducing carbon footprint.
