What is the difference between a CRM and a CDP, and how do they support marketing?

• A. CRM stores customer interactions and sales data; CDP unifies data from multiple sources for analytics and campaign targeting; both support segmentation and personalization.
• B. CRM unifies data from multiple sources; CDP only stores contact details.
• C. CRM is for analytics; CDP is for storage.
• D. CRM and CDP are identical.

Answer: (A)

CRM and CDP differ in how they handle data and enable marketing actions. A CRM stores customer interactions and sales data—think contact records, deals, tasks, support history—primarily to manage relationships with known customers and guide the sales process. A CDP, on the other hand, ingests data from many sources (website and app behavior, ads, emails, CRM records, data warehouses, etc.) and unifies it into a single customer profile using identity resolution. This creates a persistent, cross-channel view that supports analytics, audience segmentation, and activation across marketing channels.

In how they help marketing, a CRM helps tailor communication based on existing relationships, purchase history, lifecycle stage, and service interactions, focusing on known customers and ongoing engagements. A CDP enables deeper, cross-channel segmentation by combining online behavior, offline data, and cross-device signals, including anonymous visitors, and then pushing personalized messages across email, ads, websites, and apps. They’re complementary: the CDP provides rich, unified audience data for broad, consistent personalization, while the CRM maintains the relationship and sales context.
