GDPR-Compliant Email Verification: What You Need to Know

Email verification and data privacy can co-exist. With the right approach you can clean lists while remaining GDPR-compliant.

GDPR Key Principles

Lawful Basis for Processing

Article 6 of GDPR requires a lawful basis:

1. Legitimate interest — maintaining list quality
2. Consent — subscriber agreed to receive emails
3. Contractual necessity — verifying to fulfill service

Data Minimization

Article 5(1)(c) — process only necessary data. Verify the email address only. Do not access mailbox contents.
