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.
