Personal pronouns (like I, we, and you) are important in letters and memos. In such documents, it is perfectly appropriate to refer to yourself as I and to the reader as you. Be careful, however, when you use the pronoun we in a business letter that is written on company stationery, since it commits your company to what you have written. When stating your opinion, use I; when presenting company policy, use we.
Body: The body of the letter has three parts: an introduction that should explain who you are and why you are writing, a middle part that gives the details and persuades your reader to act, and a closing that tells your reader what action you expect or would like them to take. Valediction: (Left_aligned, two lines below the body) This is the line before your signature. For people whose name you don’t know, use “Faithfully yours” _ but avoid writing letters without finding out a name first.
