Question 1

What is the difference between a CMS, a CRM and a CDP?

Accepted Answer

Three systems that hold different data for different purposes, and the acronyms are confused constantly in procurement conversations.

**CMS — Content Management System.** Manages **content**: web pages, blog posts, images, product descriptions. Its purpose is letting non-technical people publish and edit without touching code.

**Examples:** WordPress, Drupal, Contentful, Sitecore.

**What it holds:** pages, media, templates, publishing workflow and permissions.

**A headless CMS** separates content storage from presentation, delivering content via API to a website, app or anything else — useful when the same content must appear in several places.

**CRM — Customer Relationship Management.** Manages **relationships and interactions**, primarily for sales and service.

**Examples:** Salesforce, HubSpot, Microsoft Dynamics, Pipedrive.

**What it holds:** contacts and accounts, the pipeline of deals and their stages, activity history — calls, emails, meetings — support tickets, and notes entered by people.

**Its defining characteristic:** it is largely **manually maintained** and organised around **known individuals** and the commercial relationship with them. It answers "what is happening with this account?"

**CDP — Customer Data Platform.** Unifies **behavioural data** from many sources into a single persistent customer profile, and makes it available to other systems.

**Examples:** Segment, Tealium, Adobe Real-Time CDP.

**What it holds:** events from the website, app, email, purchases, support and offline sources — automatically collected rather than typed in — resolved into one identity per person through **identity resolution**.

**Its defining characteristic:** it is built for **unifying and activating** data, pushing audiences out to advertising platforms, email tools and analytics.

**How they relate.** A CRM knows a customer exists and what your team discussed. A CDP knows what they actually did, across every channel. A CMS knows what content they were shown.

**Overlap is real and increasing** — vendors add adjacent features, and a small organisation may reasonably use one tool for several jobs.

**A DMP** is a fourth, older category for anonymous advertising audiences, largely displaced by CDPs.
