Email compliance: CAN-SPAM, GDPR, HIPAA and consent

Email compliance involves following legal and regulatory standards when collecting, storing, and verifying email addresses. These rules vary by region and industry, affecting how you manage consent, handle personal data, and maintain email deliverability. Understanding the core regulations—such as CAN-SPAM, GDPR, HIPAA, and relevant data privacy laws—is essential for organizations that send emails or collect email data.

CAN-SPAM requires clear identification of senders, accurate subject lines, and functional unsubscribe mechanisms. Violations can result in penalties and damaged sender reputation. GDPR governs how personal data, including email addresses, is collected, stored, and processed in the EU, emphasizing consent and data subject rights. HIPAA imposes strict rules on protected health information, requiring secure handling and verification of email data in healthcare contexts.
