Marketing consent management is a CRM feature that enables businesses to track, store, and manage customer consent preferences for marketing communications. This function ensures compliance with global data privacy regulations such as GDPR, CCPA, and CAN-SPAM by providing opt-in and opt-out mechanisms for email, SMS, and advertising campaigns. Consent tracking tools allow businesses to document permissions, automate preference updates, and generate compliance reports. By implementing transparent marketing practices, businesses build customer trust, improve deliverability rates, and reduce legal risks associated with unauthorized communications.
