If you want to build a list of potential customers, you generally have to be a little bit more strategic, and be prepared to invest a little money to "buy" your list. As a rule, people will only be willing to give you access to their inbox if there is something in it for them.

Many options for collecting new contacts exist from running small in store promotions to large scale advertising where entrants go onto your potential customers list.

As an example, a resort might run a promotional campaign in a newspaper, offering the chance to go into the draw for 3 nights accommodation simply by going to their website and signing up for their Accommodation Specials Newsletter.
