It Works Like This - One trick the expert affiliate marketers have learned is to have there own network of mailers. You can join most safelists, traffic exchanges or other mailers for free. You may only be able to mail once a week or every 3 days, but if you belong to 20 or more the mailings add up. After using them for a while you may even want to upgrade at the ones you like. I try to upgrade to a lifetime, one payment membership. This gives you a lifetime of mailings that you can mail any of your programs to.
Below are just some of the programs I use. I can mail to over 200,000 with 1 click and this is in just one of the programs that I have upgraded in. That's "Front Page Mail". It is listed 3rd below. All programs are free to join and a lot of them give you free ad credits for joining.
