Formal communication is on the wane in modern life, but there are still times when it's the only correct way to reinforce a connection or convey information. If you're applying for a job, looking for a recommendation, or expanding your network, err on the side of formality. Don't let the slightly archaic feel of a formal business letter tempt you into using flowery, outdated language.
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.
