Hello, right now I am using aweber email marketing tool, though am looking for a more flexible solution. I have around 24 000 leads and contacting them daily, 1-5 times per day. I use affiliate marketing campaigns. Is there some solution you could offer? Usually bounce rate is under 1-2%, and spam rate is under 0.1%. My list opted in at various webforms around the internet. Will wait for your insights or offers, thanks!
