List broker

A list broker is an individual or a company that maintains a list of prospective customers, including their names and contact details. Brokers sell lists to brands launching marketing campaigns, enabling brands to reach and acquire the maximum number of recipients.

Besides connecting clients with prospects, a list broker provides a narrowed directory of consumers and businesses in an area and targets them based on demographics (age, income, and gender) or firmographics (annual sales and number of employees).
