I was thinking the other day and I believe I have a way to generate 500+ new opt-in email list subscribers every day or so. These will be highly targeted leads generated without scraping or buying other lists, all are real people and are niche targeted. How many subscribers do I need to start making a profit and what kind of income should I expect monthly with a list of 10,000 or so emails? I am planning to use clickbank products but is there anything better to sell through email lists? Thanks.
