The outbound method involves a proactive attempt to reach out to your audience. This usually begins with purchasing lead lists. You then contact these leads by calling them directly (cold calling) or sending them physical mails (direct mail). For a wider reach, businesses look beyond lead lists and use billboards, print ads, television ads, and radio ads. The emphasis here is on budget, media connections, and how much marketing muscle you can flex.
Sales leads are generated on the basis of demographic criteria such as FICO score (United States), income, age, household income, psychographic, etc. These leads are resold to multiple advertisers. Sales leads are typically followed up through phone calls by the sales force. Sales leads are commonly found in the mortgage, insurance and finance industries.
