I am in need of some help. I have never done much with email marketing and now am collecting over 100 emails per day. These are not opt-in emails but they are targeted active users. I was wondering what the best email service for my situation would be. I know mailchimp and aweber charge more for the more subscribers you add and since mine aren't opt-in, I feel this is not the best way to go. I only play to send 2-4 emails per week or maybe set up auto-responders for it. Any guidance would be awesome.
