List provenance and permitted use
Public voter-file access, campaign signup information, partner referrals, and purchased records have different provenance. Keep those categories distinguishable after import.
Putting the guide into practice
Attach source identifiers and dates to the import, review the original disclosure or agreement, and reconcile suppression before generating the send audience.
- Origin
- Collection terms
- Permission evidence
- Suppression merge
Limits and review decisions
Do not label a list compliant merely because a vendor sold it or a government published it. Evaluate both access rights and the intended messaging use.
