As postage rates continue rising, it is critical for mailers to help their clients minimize postage. 1-PASS Prep (1PP) makes it easy to save money on commingling by taking advantage of the “one-pass” commingling” process offered by some comminglers. With one-pass commingling you must sort mail based on your commingler’s sort schemes. This allows them to bypass the “first pass” sort that divides a mailing into different processing schemes. This saves the commingler a lot of time and money which enables them to charge lower commingle fees.
