A business letter is a formal communication from an organization to its customers, the general public for their information, another Company or the Authorities. It is often written in a standard format, and in formal language, compared to a private letter between two people who are well known to each other. The business letter will show things like the address and best way to communicate with the business - by return letter , e-mail or telephone. In general, the letter will be directed to a specific person and be about one topic. Sometimes, the business letter will be looking for a response, but might be to give important information about an up-coming change of address or telephone number. The letter might give information about new developments - a new website; launch of a new product. To allow the sender to handle any response more efficiently, the business letter might contain key information such as an internal reference from the sender or related to the product in question.
