There are several reasons that you may need to draft a formal business letter. Business correspondences, letters to clients or employees, submitting opinions to business decision makers, are among the most popular.
Watch your voice: The trick to writing a formal business letter it to control your tone. You want to come across confident, courteous, and sincere. Finding that balance can be a little tricky.
State connections: If you have a business or personal relationship with the reader, it’s a good idea to establish that right away. In your next paragraph or two, you can make your statement, and discuss supporting examples.
Get to the point: Explain what you seek as quickly as possible, given the context of the letter, situation, and relationship between you and the reader.
Be appreciative, but don’t forget your purpose: Your last paragraph should contain a call to action, and thank the reader for their time.
