Telemarketing is the process of using the telephone to generate leads, make sales, or gather marketing information. Telemarketing can be a particularly valuable tool for small businesses, in that it saves time and money as compared to personal selling, but offers many of the same benefits in terms of direct contact with customers. In fact, experts have estimated that closing a sale through telemarketing usually costs less than one-fifth of what it would cost to send a salesperson to make a sale in person. Though telemarketing is more expensive than direct mail, it tends to be more efficient in closing sales and thus provides a greater yield on the marketing dollar. Telemarketing is especially useful when the customers for a small business's products or services are located in hard-to-reach places, or when many prospects must be contacted in order to find one interested in making a purchase. Although some small businesses operate exclusively by telephone, telemarketing is most often used as part of an overall marketing program to tie together advertising and personal selling efforts. For example, a company might send introductory information through the mail, then follow-up with a telemarketing call to assess the prospect's interest, and finally send a salesperson to visit. Lead Generation Through telemarketing, a company can compile and update lists of customer prospect leads and then go through these lists searching for sales leads. Telemarketing can screen the leads and qualify them according to priority, passing the best leads to the field sales force for immediate action. The inside sales force also can identify the decision maker with the buying power and set up appointments for the outside sales force.
