Subject: It is a brief statement mentioning the reason for writing the letter. It should be clear, eye catchy, short, simple, and easily understandable. The Greeting: It contains the words to greet the recipient. It is also known as the salutation. The type of salutation depends upon the relationship with the recipient. It generally includes words like Dear, Respected, or just Sir/Madam. A comma (,) usually follow the salutation. The Body Paragraphs: This is the main part of the letter. It contains the actual message of the sender. The main body of the mail must be clear and simple to understand. A body of the letter is basically divided into three main categories.
When your letter is to more than one person, write out all of their names separately, separating them with commas. For example, "Dear Mr. Hobbes, Ms. Luxe, and Mr. Hopman." For married couples, if one person in the couple has changed his or her name, you only need to use the last name once. For instance, "Dear Mr. and Mrs. Smith."
