Your business communications reflect the professionalism of your company. The stationery should reflect the type of business you conduct. For example, a law firm, accounting practice or investment service company presents an image of trust worthiness and stability, while a marketing firm is more cutting edge and colorful. Since the advent of the Internet, email, live chat and private messaging have become more prevalent, and letters have become more informal. But it's still prudent to follow the correct layout for business letters.
