An Email Cease And Desist Letter is a critical legal tool used when formal intervention is required to stop unwanted, harassing, or illegal email communications. This document, governed by Hong Kong law, is typically employed after informal requests to stop have failed or when the nature of the communications requires immediate formal action. The letter must comply with Hong Kong's legal framework, particularly the Unsolicited Electronic Messages Ordinance and Personal Data (Privacy) Ordinance, while clearly documenting the offensive behavior, stating demands, and outlining consequences. It serves as both a formal warning and potential evidence in future legal proceedings if the recipient fails to comply with the stated demands.
