This document provides guidance on writing official emails. It outlines a 4-point framework for structuring emails: introduction, details, response/action, and close. The introduction should set the context, details should provide all relevant facts in paragraphs, response/action should indicate what the reader should do and any deadlines, and the close can be a simple one-liner. An example email applying this structure is included. Dos include answering swiftly, using proper structure, and only discussing positive topics. Don'ts include overusing reply all, unnecessary attachments, and negative or biased language.
