Prepare for the Upcoming Postage Rate Increase

5. Look at ZIP+4/Carrier Coded mail. Deduct non-codeable records from your list rental invoice. Non-codeable records don’t qualify for postal discounts and generally are less deliverable and less responsive.

Also, be sure your list rentals and housefile have been NCOA’d recently. If you do split tests, look at the net benefit of selective binding to keep the mailing in one ZIP stream. This will maximize your postal discount — as opposed to separate ZIP streams, which are more costly. (At quantities of 300/M or more, it’s generally more cost-efficient to selective bind.)
