What are currently the best sources? I am looking for a good list with active emails, at least 1 million records. Does anyone have any lists to share? In exchange I will give you information money can't buy. How to set up email server infrastructure, what software to use, how to get free accounts with ESPs and send (until you get banned and have to create a new account), how to manage IP reputation, how to run CPA offers in email, how to monetize email newsletters, etc. Few people have FIRSTHAND experience in this. Thanks.
