I have used iContact (aff link included whee) for about a year for my casino related traffic. Like you, I got booted from Constant Contact which led me where I am. I have been very happy with their services and reporting capability of mailers. I use them to send out newsletters 2-3 times a month. They also have a 15 day free trial for up to 250 subscribers so you can “try it before you buy it” so to speak. Take a look and see what you think. I also specifically got approval for my content via email before I signed up to make sure I wouldn’t have to move my list again.
