I checked it out. I do use a very cost effective Auto Responder to great effect. It is 17.95 a month for as many campaigns, emails and/or subscribers as you want. There is also a great affiliate program that to date I am making over 100$ a month using a tool I would pay to use.
Check it out:
The reason I use an auto responder is to provide value and build trust with my list. You cannot just have a list of names and think you can sell to that list. You must provide value content with a consistency that does not annoy but so that they do not forget.
BTW I am going to pay you $10.00 and Join your list program. It provides more than the list capability and I think I will be able to use it to grow my Real List.
