Digital Marketing
Data Minimization
Data minimization is the principle of collecting only the personal data that is strictly necessary for a specific, stated purpose. It is a core requirement of major privacy regulations and reduces both compliance risk and data storage costs.
Examples
A newsletter signup form removes optional fields for phone number and birthday, collecting only email and name to reduce unnecessary data exposure.
Best Practices
Audit every data collection point in your marketing stack quarterly, eliminate fields that do not directly serve a defined business purpose, and automate data retention limits.
