When do you actually need a CDP?

You need a CDP when your customer data is scattered across multiple tools (like your CRM, email platform, analytics tool, and help desk) and you cannot create a unified view of a single customer's journey. If your marketing team struggles to personalize campaigns because they don't know what a user did on your mobile app versus your website, a CDP is designed to solve that problem by collecting and stitching that data together.

What's the difference between a 'packaged' and a 'composable' CDP?

A packaged CDP is an all-in-one software that handles data collection, storage, identity resolution, and activation in a single platform. A composable CDP, by contrast, is a modular approach where you use your existing data warehouse (like Snowflake or BigQuery) as the data storage and identity resolution layer, and then use specialized tools for activation (like a 'reverse ETL' tool). Packaged is faster to set up; composable offers more control and can be cheaper if you already have a mature data warehouse.

How to choose

1. 1First, map your existing customer data sources and marketing destinations to identify required integrations. A vendor's connector library is a critical decision point.
2. 2Second, evaluate your team's technical skills; developer-centric tools like Segment and RudderStack require more engineering resources than marketer-friendly UIs like Simon Data.
3. 3Finally, model your costs based on user or event volume, as pricing models vary significantly between MTU-based (Monthly Tracked Users) and event-based billing.

What is the difference between a CDP and a CRM?

A CDP unifies data from many sources to create a single customer profile, while a CRM primarily manages direct customer interactions like sales and support. A CDP collects anonymous user data (like website visits) and known customer data (like purchases), whereas a CRM almost always deals with known customers and leads. The CDP often feeds cleaner, unified data into the CRM.

How much does a Customer Data Platform cost?

CDP pricing varies widely, from around $500 per month for startups to over $500,000 per year for large enterprises. Most mid-market plans fall in the $2,000 to $15,000 per month range. Pricing is typically based on the number of monthly tracked users (MTUs) or the volume of events processed.

What are the key features to look for in a CDP?

The most important features are data collection connectors for your specific tools, identity resolution to stitch user profiles, audience segmentation tools for marketers, and activation connectors to send those audiences to your marketing platforms. Real-time data processing and strong compliance features for regulations like GDPR are also critical.

How long does it take to implement a CDP?

Implementation time can range from a few weeks to over six months. A simple implementation connecting a website and one or two marketing tools might take 30-60 days. A complex enterprise rollout connecting dozens of legacy systems can take 6-9 months and require significant data engineering resources.
