Practice where an advertiser or publisher pays the owner of a list for access to the entire email list they possess. The publisher or advertiser would then be the owner of the list and send it over to their system to send emails. This practice is usually one of the worst ways to gain customers and may result in high complaint rates and spam trap hits. The purchased lists are usually of poor quality.
