If you are writing to someone who has a doctorate or medical degree, use the abbreviated form: "Dr." However, for other titles, such as professor, judge, rabbi, etc., write out the full title and capitalize it. For example, your salutation in a letter to a judge would be, "Dear Judge Barnard." Or, if your correspondence was with a rabbi, you might write, "Dear Rabbi Williams."
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.
