Privacy Aware Mass Mailing - Verify and manage GDPR-compliant email consent
About PAMM
The PAMM (Privacy Aware Mass Mailing) Thunderbird add-in lets you verify that marketing emails you receive have proper GDPR-compliant consent. This add-in checks digital signatures and consent tokens embedded in emails to ensure they've been sent legally and with your explicit permission.
Note: This add-in is part of a research project demonstrating how email consent verification can be cryptographically enforced.
