This invaluable machine allows us to barcode and sort letter-sized mail at speeds up to 20,000 per hour. It also enables us to COMINGLE MAIL. What does that mean? Comingling mail from multiple clients with multiple postage payment methods (meter, permit indicia, precancelled stamp) means our clients qualify their mail for lower postage rates than they would be able to achieve on their own by becoming part of a larger mailing. With 30 sort pockets and amazing software, our mailings our sorted to the finest level for nationwide distribution.
