If you are replying to an email that contains classified information, how should the banner of your unclassified response appear?

When replying to an email that contains classified information, it is essential for the banner of your unclassified response to clearly indicate 'Unclassified.' This designation serves multiple purposes: it helps maintain the integrity and classification levels of the information being communicated, ensures that the recipient understands the classification status of your message, and upholds the standards of information security. By clearly marking your response as unclassified, you prevent any potential confusion regarding the sensitivity of the information you are sharing and reinforce the importance of adhering to proper marking protocols when dealing with classified correspondence.
