Customer Data Platform.

A Customer Data Platform (CDP) is a technology that collects, unifies, and activates customer data from multiple sources (website behaviour, email interactions, CRM records, offline purchases, app usage, and third-party data) into a single, persistent customer profile. Unlike a CRM (which is primarily for sales interaction management) or a DMP (which handles anonymous, third-party ad targeting data), a CDP is designed to handle known, first-party data at scale and make it available to any connected marketing tool.

What CDPs Enable

CDPs enable: accurate cross-channel attribution by linking the same customer's interactions across devices and channels; real-time personalisation powered by unified customer profiles; advanced segmentation that combines online and offline data; audience syndication to advertising platforms using first-party audiences; and data governance that ensures privacy compliance across all downstream uses of customer data.

CDP vs. DMP vs. CRM

The key distinctions: CRMs manage relationships with known contacts in a sales context; DMPs (Data Management Platforms) handle anonymous, third-party cookie data for advertising, fading in relevance as third-party cookies disappear; CDPs unify first-party known and anonymous data into persistent profiles for marketing activation. Many organisations use all three, with the CDP as the central data layer that feeds the others.
