Which method of prospecting has the highest wasted audience?

Question

Quizplus · Accepted Answer

Listings of possible customers in a local telephone directory have the highest wasted audience because they include a broad and unfiltered range of individuals or businesses, many of whom may not be interested in or relevant to the specific product or service being offered. This method lacks the targeting present in referrals, industry-specific listings, or lists of former customers, leading to a higher proportion of uninterested parties.
