How do I ensure compliance with data privacy regulations like GDPR and CCPA when using AI in marketing?

Ensure GDPR and CCPA compliance in AI marketing by minimizing personal data, documenting lawful basis, honoring consumer rights, and auditing vendors regularly. Under GDPR, document a lawful basis (e.g., consent or legitimate interests) and execute Data Processing Agreements (DPAs) with AI vendors; under CCPA/CPRA, provide “Notice at Collection” and enable opt-out of “sale” or “sharing” for cross-context behavioral advertising. TSC’s Chief Strategy Officer JJ La Pata notes that “privacy compliance fails most often at the model input layer—log every data field you send to AI, why you send it, and how long you retain it.” As a concrete control, set retention limits (e.g., 30–90 days for AI prompt logs) and run quarterly Data Protection Impact Assessments (DPIAs) for high-risk AI use cases, last verified for 2026 planning cycles.
