A letter of inquiry | Management homework help

Inquiry letters ask for information about a product, service, or procedure. Busi- nesses frequently exchange such letters. As a customer, you, too, have occasion to ask in a letter about a special line of products, the price, the size, the color, and delivery arrangements. The clearer your letter, the quicker and more helpful your answers are likely to be.

It states exactly what information the writer wants.
It indicates clearly why the writer must have the information.
It keeps questions short and to the point.
It specifies when the writer must have the information.
It thanks the reader.
