The implementation of regulations such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) has significantly impacted email marketing strategies. These laws require businesses to obtain explicit consent from users before sending them marketing emails. As a result, marketers need to be more transparent about how they collect and use data, and they must provide easy options for users to unsubscribe. Failure to comply with these regulations can lead to hefty fines, making it crucial for businesses to adapt their email marketing practices accordingly.
