I'm complete newbie when it comes to email marketing and would really appreciate an advice from experienced members. I got quite good list of few thousand emails and we sent our first testletter using iContact and Mailchimp. We did few bucks with sales and basically quite happy with the start. Mailchimp performed better but they blocked us when trying to send second email with different offer, should have been offer from same niche or something. Anyway, now we are thinking of scaling it and buying co-reg leads. I understand that the quality will be a lot worse than with our own list, but it's more easy to scale if it works. The problem is, what mailing service to use? Or use VPS and some mailing software? If so, any good software you could recommend? The problem, as I understand it, is to staying out from spam folder - any tips for that? If using your own VPS setup, how many proxies to use? Any other advice for the setup? I'm not asking anyone to spoon feed me, just asking to get some basic tips and to point me in right direction. I tried to search, but didn't really find what I was looking for.
