A statement appended to electronic mail messages, designed to protect sensitive information from unauthorized disclosure. It typically alerts recipients that the message contains privileged or confidential information, and instructs them to notify the sender immediately if they receive it in error. An instance might read: “This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed. If you have received this email in error, please notify the sender immediately and delete this email from your system.”
The inclusion of such a disclaimer serves as a deterrent against the unlawful distribution or utilization of proprietary data. While its legal enforceability can vary depending on jurisdiction and specific circumstances, it provides a formal indication of the sender’s intent to maintain confidentiality. The practice has become widespread as a means of reinforcing data protection policies and mitigating the risk of breaches in communication.
