All of my email marketing so far has been to opt-in subscribers via aweber.
As part of another venture I want to email prospects who have contacted us to inquire about our services. However, I don't just want to send a newsletter, I want to use an auto responder similar to aweber so that I can improve the offer (or the price) as time goes on.
I also need to be able to view which was the most recent message, so that I can know what the offer they received was.
Does anyone else do this, and if so how do you do it and what do you use?
I can't use aweber as they need the recipients to confirm subscription, which they have not because they contacted us out of the blue.
