Customer data platform
Software that collects customer data from many systems, links it into one profile per customer and makes those profiles available to other tools.
A customer data platform (CDP) is software that collects customer data from many systems, such as ecommerce, point of sale, apps, email, customer service and the loyalty program, links the records that belong to the same person into one profile, and makes those profiles available to other tools for segmentation, personalization and analysis.

What does a CDP do?
It has three jobs. It ingests data from each source, in batches or in real time. It resolves identities, matching records that belong to the same customer through identifiers such as email address, phone number, loyalty number or device. And it activates the result, building audiences and sending profiles or segments to marketing, advertising, service and analytics systems. Many CDPs also include their own segmentation tools and predictive scores.
How does a CDP work with a loyalty platform?
They do different jobs. The loyalty platform is the system of record for the program: it holds the points ledger, applies earning and tier rules and processes redemptions. A CDP does not calculate points or tiers. It takes loyalty data, such as tier, balance and recent earning, as one input, combines it with everything else and helps the business decide whom to contact and with what. Loyalty data inside a CDP improves targeting, but a CDP without a loyalty engine does not run a program.
What should you check before buying one?
Start from use cases: which decisions will a unified profile improve, and which systems need it? Check how the CDP resolves identities and whether you can see and adjust its matching rules. Check how fast loyalty events reach it, since a balance or tier shown in a message must be current. And check consent handling: each customer’s permissions should travel with the profile to every system it feeds. Privacy law applies across all of them. The California Consumer Privacy Act, for example, gives consumers the right to know what personal information a business collects about them and to have it deleted, with some exceptions, which is easier to honor when one profile links all of a customer’s records.
What are the common problems?
Buying the platform before the data is ready is the first: if identifiers are inconsistent across sources, profiles end up split or wrongly merged. Overlap is the second, because data warehouses, CRM systems and marketing suites now offer similar functions. The third is slow activation. A CDP that builds good profiles but cannot feed the channels that use them adds cost without changing anything members see.
