Which of the following best practices should you apply when forwarding an email?

When forwarding an email, it is crucial to prioritize the privacy and confidentiality of the individuals involved in the original correspondence. Removing other people's email addresses serves this purpose by ensuring that sensitive information is not exposed to unintended recipients. This practice helps to maintain trust and complies with privacy standards, which is especially important in professional settings where protection of personal data is paramount.

While maintaining the original formatting can be important for clarity, it does not address privacy concerns like removing email addresses does. Additionally, adding unnecessary comments can detract from the original message's intent and potentially confuse the recipient. Ignoring a personal greeting might lead to a lack of professionalism, but it is less critical than preserving privacy. Therefore, prioritizing the removal of personal information aligns closely with ethical communication practices.
