Sales letter sent to someone who has made an inquiry inviting the inquirer to make a purchase; part of the inquiry conversion process. This process is generally used for expensive items requiring a lot of information and thought before a purchase decision is made, such as an automobile or an insurance policy. Follow-up letters differ from other promotional mailings in that they are mailed in response to an inquiry on an individual basis in contrast to being mailed in bulk on a date determined by the mailer. The first follow-up letter in a series is usually the most detailed, while subsequent efforts highlight individual benefits. See also inquiry and follow-up.
