Some background on why MailChimp asked me to leave. I run an online store that launched in late October. We have done four campaigns in that time each with a list size of 500, 1000, 3000, and 90,000. Due to our rapid rate of growth every mailing has essentially been a first time send to the list. Unsubscribes and bounces are removed right away. I also understand the laws and that the rates the list saw were just too high. All of our lists track the date/time and IP address to have a proof of signup that they recommend. I even checked with them before the last send knowing I had issues, the person I spoke with said he understood and I should be okay even with the proof. Well I wasn't and I have been asked to leave. I will give props to MailChimp for not billing me this month to help with my transition.
So... with that being said I need a new home for my email marketing need.. what does everyone recommend?
