Requirements
Business Identity Information
You must display your full name, job title, business address, and phone number in every business email. This applies whether you're sending to customers, prospects, or internal staff. Hiding or omitting this information violates Article 5 of GDPR.
Data Processing Transparency Notice
Include a clear statement explaining that personal data shared via email will be processed according to your privacy policy. This primes the recipient and shows you're aware of data handling obligations. Link to your full privacy policy if space allows.

If you're sending marketing emails, include visible language confirming the recipient has consented to receive communications. Provide an easy unsubscribe or opt-out link. Non-compliance here triggers GDPR Article 21 violations.
