For some people, a day at the office is an endless succession of meetings. Arranging all of the appointments is often a secretarial duty. Although plans can be made by telephone, they are usually confirmed by letter (when time permits). The appointment letters or responses to them may be the first thing a prospective client or customer sees from your company, so to make a good impression it is important that the letter be clear, accurate and courteous.
Since appointment letters include details such as time, place and date, they have to be precise. They also should be sent in time for the recipient to respond and comply with the suggested arrangements.
