(iv) Completeness - A complete letter is one that provides all necessary information to the users. For example, while sending an order we should mention the desirable features of the goods, i.e., their quality, shape, colour, design, quantity, date of delivery, mode of transportation, etc.
(v) Relevance - The letter
