Introduction to CRM and CDP in digital marketing
CRM and CDP are becoming essential tools for Vietnamese SMEs. CRM focuses on managing individual customers. CDP unifies multi-channel data. Understanding them helps businesses optimize advertising.
What is CRM and its core role
CRM (Customer Relationship Management) helps track customer interactions. Businesses record purchase history, emails, calls. This tool builds long-term relationships. SMEs use CRM to personalize services.
For example, a fashion store uses CRM to send birthday offers. Customers return to shop 30% more. Clear effectiveness with limited budget.
You can start right away by:

How CDP works
CDP (Customer Data Platform) collects data from all sources. Website, app, social media all sync into a unified profile. CDP creates a 360-degree customer portrait.

Key differences between CRM and CDP
Many SMEs confuse CRM with CDP. They complement each other but have distinctly different functions. Understanding the difference helps choose the right tool.

CRM mainly stores data of known customers. Name, phone number, transaction history are in CRM. It does not handle anonymous data from web.
CDP collects data from everywhere, including anonymous visitors. CDP tracks web browsing behavior, ad clicks. The result is a more complete customer profile.
| Criteria | CRM | CDP |
|---|---|---|
| Data source | Known customers | Multi-channel, anonymous |
