This document provides guidance on writing emails of inquiry and replying to inquiries. It recommends using a three-part structure for inquiries: introduction, body, and conclusion. For inquiries, the introduction states who you are and what you want to know, the body asks questions, and the conclusion requests a reply. When replying, thank the person for their inquiry, answer all their questions, highlight selling points, and encourage further contact. Examples of effective inquiries and replies are also included.
