Short answer

A data management platform (DMP) is a legacy marketing technology for collecting, organizing and segmenting mostly anonymous audience data, typically keyed to cookies and device IDs, for ad targeting. DMPs have declined as third-party cookies faded, with many of their functions moving to customer data platforms and clean rooms built on first-party data.
