The best way, the cheapest way, the easiest way to build your list is to join a Giveaway as a contibutor.

You will give away one of products., and in return people agree to join your mailing list.  You can usually add more than one gift and get more sign ups. I have personally used this method to add 100’s of new subscribers to my list.

The key is join a list from one of the reputable promoters, they will help generate tons of traffic to the giveaway and that exposes your product to thousands of people.

It is a fantastic way to build your list…The usually have an upgrade option, for a small fee, you can list one of your products for sale..So you can generate cash as well as sign ups for your mailing list.
