Safelists are in fact nothing more
than a group of individuals, who agree to receive and send email messages to each other. The fact that they agree to receive email make these lists "safe", and hence the name safelist.
A safelist can be used to advertise web sites, business opportunities, affiliate programs and so on and so forth. A safelist works well for people who don't have a web site, and can't build
their own opt-in list and also can serve well as an additional advertising option for people who already have their own safelist! A safelist script got to have many advanced options which will
allow you to have full control over every aspect of your safelist.
