The ZIPs worth the postage

We set aside the sales your ads paid for and the sales that come from a place just being big, then rank what is left. Your mail goes to the communities pulling in new customers, not the ones that are simply large.

Common questions

Do you print or mail for me?

No. We are the targeting layer. We hand you the ranked, mail ready list and you run it through your own printer or mail house.

EDDM or addressed mail?

Both. The list comes formatted for USPS EDDM routes and for addressed drops, so you can pick the format that fits the campaign.

How do I know it worked?

We build a holdout in. You mail the targeted ZIPs, keep others back, and we measure how much more the mailed markets grew.
