Am I charged for unmatched data in Universal Onboarding?

Pay only for matched, addressable data when you onboard.

No. You only pay for matched IDs and the observations traversed to reach a deliverable ID in your Universal Onboarding subscription. You do not pay for any unmatched IDs.

This means that you can upload as many IDs as you want to forecast an instant match rate while only paying for delivered IDs that you actually receive.
