A Customer Data Platform (CDP) is software that centralizes and organizes customer data from different channels into a single unified profile. Unlike CRMs and DMPs, a CDP collects information in real time and allows for more precise audience segmentation. Platforms such as Segment, BlueConic, and Tealium help integrate data from web browsing, social media, emails, and purchases, providing a 360-degree view of the customer. This enables the personalization of marketing campaigns and improves the user experience. Its use is key for strategies based on data-driven marketing.
