How to Write a Formal Letter
Formal letters--They can shape others' perceptions of you, inform the reader of a serious issue, or get you a job. There are two main types of business letter styles: block style and Administrative Management Style (AMS). Block style is the most commonly used formal letter format; it has a salutation and closing, and is good for letters to businesses you are applying to or someone you have met before. AMS style is more succinct and better for internal memos and situations where you have to be very direct.
