Over time, the popularity of email marketing campaigns resulted in personal email inboxes that were overflowing with the latest and greatest offers. Email campaigns grew and people grew tired of them. Laws that allowed customers to unsubscribe breathed new life into email marketing campaigns as customers could easily pick and choose the companies they were interested in.
Lead generation is the method of getting inquiries from potential customers. In the old pre-Internet days of sales, lead generation occurred at places like trade shows – visitors to a company's booth would fill out a card with their contact information and turn it in to receive a call back from that company's sales team. Since the rise of the Internet, many businesses use their websites as a lead generation option. Email also offers lead generation potential, since companies can buy another company's email marketing list or pay them to promote the company on their own marketing emails.

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. 

Landing Pages - The best lead generation tool of all is your product. If you have a compelling product that solves a major pain point, visitors will want to provide their contact information even without any incentives. Presenting your product in the most attractive way is often done through landing pages or sales pages, which help educate and convert prospective customers. Landing page optimization is the key to making sure you are getting the most out of these pages.
Online surveys: Consumers are asked to complete a survey, including their demographic information and product and lifestyle interests. This information is used as a sales lead for advertisers, who purchase the consumer's information if provided. The consumer may 'opt-in' to receive correspondence from the advertiser and is therefore considered a qualified lead.
