They say that money is on how huge your mailing list is. You can build your mailing list several way by joining these safelists and setting up your auto responder. A safelist is a sort of mailing list exchange where the member like you and me agreed to receive emails from other members and while they click/read on your email and other members they get a credit which in turn can be converted into sending an email to the members. For example you have 1000 credits, it means that you can send to 1000 members depending on the credit conversion of that specific safelist

See the possibilities. When offline, I was advised to have at least 100 contacts per day knowing your product by that time there's no internet so it's hard getting leads or business prospects for anything you wish to sell but in these times, above-mentioned safelists I just given a total of 93,828 business prospects.
