This ebook by Jerry is an excellent guide for setting up and using safelists.
As described in the the book. A safelist is a membership site which allows it’s members to exchange email
ads with one another.
That means that you would be able to email an advertisement to the membership of a safelist and in exchange you
would agree to receive email ads from other members.
An effective free source of traffic.
This is a list of Safe Lists I use …
I ungraded in a couple but use the free membership in all the others.
I agree it is time consuming having to click for credits to be able to mail but as my business grows I upgrade in the lists I find most beneficial.
