In business operations, maintaining contact with existing customers is a natural need. However, from a personal data protection perspective, the fact that a business has had prior transactions with a customer does not automatically make all subsequent marketing activities appropriate.
What needs to be reviewed is the original purpose for which customer data was collected, whether the current use still falls within the customer’s reasonable expectations, and whether the business is using the data in a way that goes beyond the original transactional context. In practice, risks often arise when data collected for transactional purposes is later used more broadly for promotional campaigns, new product marketing, or shared across multiple departments without proper internal review.
The boundary between “customer care” and “marketing outreach” should therefore not be defined solely by commercial objectives, but from the perspective of data processing purpose and the appropriateness of continued data use after the transaction.
A practical tip for marketing and legal teams:
Businesses should standardize a marketing purpose review step before launching campaigns targeting existing customers, instead of assuming that all current customers can be included in all marketing activities.
Mini-checklist:
• Review the original purpose of customer data collection;
• Distinguish between transactional/customer care activities and extended marketing activities;• Verify the scope of data used in the campaign;
• Restrict internal access to and use of customer lists;
• Document the internal basis for using data in each campaign.
Operational convenience in marketing should not replace a proper review of data processing purposes in each specific context.
Legal reference:
Law on Personal Data Protection No. 91/2025/QH15 and its implementing regulations, particularly provisions on data processing principles, purpose limitation, transparency, and responsibilities of data-processing organizations.
