What are Safelist Mailers? Let us say you need to market a product to your list , but , you don’t have a list. Well, now you do. Simply sign up for any of these type of programs and you will be able to market to a list. Here is the catch, you will get a lot of email into your inbox. What you do is read the emails and click the links. Then you will have some kind of timer to wait through in order to have time to view each ad. You earn credits for viewing the emails and then can send out your own email. Each site has different requirements.
