We read your own customers, set aside the effect of ad spend and sheer size, and rank the areas that are catching on. Your EDDM coverage follows growth instead of guesswork.
The list lines up with USPS EDDM routes and comes with a loading guide, so you can go from our file to a booked drop without wrestling the data.
Keep a few areas out of the drop, and we show how much more the covered areas grew. You learn which routes to keep before you spend on the next round.
Every Door Direct Mail is a USPS service for mailing every address on a postal route without a mailing list. porterzip tells you which routes are worth covering.
No. EDDM works at the route level. We use your own customers to rank the routes, and your contacts never leave your file.
Yes. We build a holdout in so you can see how much more the covered routes grew than the ones you left out.
