Marketing data governance is the process of ensuring data integrity, security, and compliance within CRM-driven marketing initiatives. It involves implementing policies, standards, and controls to maintain accurate, clean, and legally compliant customer data. Businesses use data governance frameworks to prevent duplicate records, enhance privacy protection (GDPR, CCPA), and ensure proper attribution of marketing efforts. By maintaining high-quality CRM data, organizations can optimize campaign performance, personalization efforts, and audience segmentation. A structured data governance strategy leads to better decision-making, increased regulatory compliance, and a more trustworthy customer database.
