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.
My list is already double opt in, and I would prefer not to have it triple opt in. Does this service send out an email requiring your customers to opt in yet again?
Nope, although you can request it to if you wanted. Your initial upload of addresses is imported directly and you can send out stuff immediately. New additions to the lists via a web form entry can be configured for either immediate adds or double opt ins.
