Include Information about the Company: One must clearly state the name and the address of the company. Try to use a letterhead of the company for any business use. Include the date: Writing the date helps the person to have a record of the on_going business. Add the Recipient’s Information: In a business letter, one must clearly type the name, address, and the job title of the recipient to remove any ambiguity. Choose a Salutation: It is a way of showing respect towards the recipient. One can also use ‘To Whom It May Concern’ if he doesn’t know the person addressed.
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."
