CDP vs CRM vs marketing automation: which system does what
A CRM manages relationships: the contacts, companies, deals and conversations your sales and service teams work with. A marketing automation platform runs campaigns: it sends emails and other messages, triggers journeys and scores leads. A customer data platform (CDP) unifies data from all your systems into one profile per customer and makes it available to every other tool. They overlap, but each answers a different question, and most growing organisations end up using two or all three.
This article compares the three side by side, explains where they overlap and helps you decide which you need first. For the basics of each, see our guides to what a CRM is and what a CDP is.
How do a CRM, marketing automation and a CDP compare?
What does each system do?
CRM
A customer relationship management system records who your customers and prospects are and what you have agreed with them. Salespeople use it to manage deals and follow-ups; service teams use it to handle questions and cases. Its strength is the relationship history. Our article on why CRM suits B2B companies explains why it is often the first system a growing sales team needs.
Marketing automation
Marketing automation handles communication at scale: email campaigns, triggered journeys, forms, landing pages and lead scoring. Email marketing software is the core of most marketing automation platforms. Its strength is acting on data quickly and consistently. Read about the benefits of marketing automation.
Customer data platform
A CDP collects data from every system that touches the customer, matches it to the right person and keeps one persistent profile. It then makes those profiles and segments available to the tools that act on them. Its strength is a complete, consistent view. The analyst David Raab first described the category in 2013, as our CDP guide explains.
What is the difference between a CRM and marketing automation?
A CRM is organised around people and deals; marketing automation is organised around messages and journeys. The CRM tells a salesperson what was said in last week’s call. Marketing automation sends the follow-up content and notices when the contact visits the pricing page.
They overlap on contacts, and that is where problems start if they are not connected. The essentials to keep in sync are new leads and their source, lead scores and lifecycle stage, consent and unsubscribes, and email activity on the contact record. When that works, sales sees which leads are warming up and marketing knows which contacts are in an active deal. Our article on aligning sales and marketing with CRM covers the working agreements behind it.
What is the difference between a CDP and a CRM?
A CRM mainly holds data that people enter or log: contact details, notes, deals, cases. A CDP mainly holds data that systems generate: page views, product views, purchases, app events, email clicks. It also connects anonymous behaviour to a known person once they identify themselves, for example by logging in or clicking an email.
Scale is the other difference. A B2B company might manage a few thousand accounts in its CRM. A retailer can have hundreds of thousands of customers, each with dozens of interactions a month. A CRM is not built to process that volume of behavioural data, and a CDP is.
The two work together. The CDP can feed behaviour and predicted value into the CRM, so service and sales see the full picture. The CRM feeds deal and service data back into the CDP, so marketing does not promote a product to someone with an open complaint about it.
What is the difference between a CDP and marketing automation?
Most marketing automation platforms have their own contact database, and for many organisations that is enough. The difference is reach. A marketing automation database serves that platform. A CDP serves every platform: email, ads, website personalisation, WhatsApp, service tools and analytics.
You start to need a CDP when the same customer looks different in each tool, or when building a segment means exporting from several systems. Another sign is wanting to act on data your automation platform cannot see, such as in-store purchases or app behaviour. Our article on starting with a customer data platform describes the first steps.
Can email marketing software replace a CRM?
For a small team with simple needs, sometimes. An email platform can store contacts, tags, custom fields and engagement history, which may be enough if you do not have a sales pipeline to manage. Our guide to email marketing covers what such a platform does well.
What you miss without a CRM is the sales side: companies with several contacts, deals with stages and values, tasks and reminders, call notes, service history and sales reporting. Signs you have outgrown the workaround include deals tracked in spreadsheets, follow-ups that slip and nobody knowing who last spoke to a customer. Our guide to spreadsheets versus CRM sets out the tipping points.
Where do DMPs, data warehouses and data lakes fit?
- A data management platform (DMP) manages mostly anonymous audience data for advertising. With third-party cookies in decline, its role has shrunk. Our article on CDP versus DMP explains the difference, and our piece on first-party versus third-party data covers the wider shift.
- A data warehouse stores structured data from across the business for reporting and analysis. Some organisations build marketing segments directly on their warehouse, an approach sometimes called a composable CDP.
- A data lake stores large volumes of raw data in its original form, usually for data science rather than day-to-day marketing.
- An ERP system runs finance, stock and operations. Our article on CRM versus ERP explains how it differs from a CRM.
Which do you need first?
It depends on how you sell:
- Sales-led B2B: start with a CRM, so deals and relationships are under control, then add marketing automation to generate and nurture leads.
- Ecommerce and retail: start with email and marketing automation connected to your shop. Add a CDP as data sources multiply and you want to personalise across channels.
- Organisations with many systems: if customer data already lives in a CRM, a shop, an app, a loyalty programme and a service desk, a CDP is often what makes the rest work together.
Whatever you choose, plan the data flows before you buy. Our guide to data management covers the groundwork, and our article on what stops companies from using a CDP deals with the common objections.
How do the three work together?
In a connected set-up, each system does its own job and shares what the others need. The CDP collects and unifies data and builds segments. Marketing automation uses those segments to send the right messages and scores the responses. The CRM receives warm leads and customer insight, and its deal and service data flows back to the CDP. Consent and unsubscribes are synchronised everywhere.
Frequently asked questions
Do B2B companies need a CDP?
Not always. Many B2B organisations do well with a CRM and marketing automation that are properly connected. A CDP becomes worthwhile when you have many data sources, a large customer base or a need to personalise across several channels from one view.
Can one platform do all three jobs?
Some suites combine CRM, marketing automation and customer data in one product. That simplifies integration, but you may accept weaker functionality in one area. The alternative is separate, specialised tools that are well connected. Either works if the data flows are designed deliberately.
