One of our clients had a complex prospect mailing with 11 different versions mailing at the same time. Because of the number of individual zip strings, there was very little postage savings. But, because PMG manages postal logistics for our clients in addition to the production, we were able to work out a plan to consolidate the mailings after they were inserted, and then truck them directly to the various bulk mail centers. The client wound up with postage savings of thousands of dollars after all.
