Frequently asked questions
Common questions about Customer Data Platform, answered.
What is a customer data platform (CDP)?
A customer data platform is software that collects and unifies customer data from many sources — website, app, CRM, transactions, email, ads — into persistent, single customer profiles that are accessible to other systems for marketing activation. Its purpose is to break down data silos and create a complete, usable view of each customer that powers personalization, segmentation, and targeting across channels.
What does a CDP do?
It ingests data from disparate sources, resolves it to unified individual profiles (matching identities across touchpoints), and makes those profiles available for activation — building audiences, personalizing experiences, and syncing segments to ad platforms, email, and other tools. Essentially it's the central hub that turns scattered customer data into a single source of truth that marketing can act on in real time.
How is a CDP different from a CRM?
A CRM manages known customer/prospect relationships and sales/service workflows, with structured contact and deal data oriented to sales teams. A CDP unifies all customer data — including behavioral, anonymous, and cross-source data — into comprehensive profiles built specifically for marketing activation and personalization at scale. CRMs manage relationships and pipeline; CDPs unify data for marketing use. They're complementary and often integrated, not interchangeable.
Why are CDPs increasingly important?
Because unifying first-party data has become essential as third-party tracking declines. A CDP creates the complete, consented first-party customer view needed to target, personalize, and measure in a privacy-constrained world, and to feed clean signals to ad platforms. As marketing leans harder on owned first-party data, the CDP's job — unifying and activating that data across channels — becomes central infrastructure.
What powers personalization in a CDP?
Unified profiles plus segmentation and real-time data. By bringing together everything known about a customer (behavior, purchases, preferences, channel activity) into one profile, a CDP lets marketers build precise segments and trigger personalized messages and offers across channels based on the full context — and keep them current as new data arrives. The completeness and freshness of the unified profile is what enables relevant, timely personalization at scale.
