What’s a Consent Management Platform (CMP)?

Consent Management Platforms collect, store, and manage user consent for data processing. They provide: consent collection interfaces (banners, forms), preference storage, consent documentation, and downstream system synchronization.

Email application: CMPs record subscription consent with required detail (what, when, how), sync consent status to ESPs, provide **preference center** functionality, and maintain audit trails for compliance demonstration.

CMPs ensure: consent is properly collected (not pre-checked boxes), documented with timestamps, synchronized across systems, and available for auditing. They're the system of record for proving legitimate data processing basis.
