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.
When you write a business document, you must assume that your audience has limited time in which to read it and is likely to skim.
