Summary
Gmail and Yahoo's new requirements mandate one-click unsubscription for commercial emails, a stricter interpretation of the CAN-SPAM Act's existing opt-out provisions. This requires implementing a List-Unsubscribe header (preferably using List-Unsubscribe-Post with HTTPS), providing a clear and functional unsubscribe link in the email body, and ensuring the unsubscribe process can be completed with a single click. While preference centers are permissible, they cannot be the sole method for unsubscribing from all emails. Compliance enhances user experience, improves sender reputation, reduces the likelihood of emails being marked as spam, and prevents potential blacklisting. Senders should adhere to the technical specifications outlined in RFC 8058 for List-Unsubscribe-Post implementation and adapt their practices to comply with these evolving regulations.
Key findings
- One-Click Mandate: Gmail and Yahoo require one-click unsubscription, a stricter enforcement of CAN-SPAM.

The one-click unsubscribe requirements from Gmail and Yahoo necessitate a non-interactive unsubscribe mechanism, typically achieved through List-Unsubscribe headers (mailto: or List-Unsubscribe-Post) and a visible unsubscribe link leading to a CAN-SPAM compliant page. It's recommended to use HTTPS links and List-Unsubscribe-Post for optimal functionality. While preference centers can be offered, a single-click unsubscribe option must always be available to comply with both CAN-SPAM and the new mandates.
