Common questions

What is EDDM?

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.

Do I need addresses for EDDM?

No. EDDM works at the route level. We use your own customers to rank the routes, and your contacts never leave your file.

Can I measure an EDDM drop?

Yes. We build a holdout in so you can see how much more the covered routes grew than the ones you left out.
