Google and Yahoo require bulk email senders to implement one-click unsubscribe functionality, primarily achieved through RFC 8058. This standard uses the HTTP POST method via the List-Unsubscribe header, enabling users to unsubscribe directly within their email client. Compliance is vital for maintaining good sender reputation, deliverability, and avoiding spam filters. Unsubscribe requests must be processed within 24 hours. While RFC 8058 is the standard, supporting 'mailto:' links can provide compatibility with older email clients. Differentiate between the technical RFC 8058 implementation and legally required unsubscribe links in the email body (e.g., CAN-SPAM). Proper testing and efficient list management are essential.
