CNIL publishes guidance on data transfer to third parties for electronic prospecting

On December 28, 2018, the French Data Protection Agency, the Commission Nationale de l’informatique et des Libertés (CNIL) published several principles to help companies comply with the General Data Protection Regulation (GDPR) while transferring personal data to their commercial partners for electronic prospecting.
