This document provides guidelines for proper email etiquette. It discusses keeping messages concise and to the point using plain text. Abbreviations and emoticons can help convey tone. When replying to emails, it's best to include the previous message for context. Threads should be trimmed as they grow to avoid large files. Sensitive information should be avoided as email is not secure and messages can be forwarded without consent. Raising emotions should be done carefully, as tone does not transmit clearly. Major taboos include typing in all caps, flaming, spamming, and large file attachments.
