Hey, Ed! The fastest way to create an email list of high-quality leads is to reverse engineer the process. Specifically, that means:

1. Plan the big-ticket thing you want to sell and who you want to sell it to
2. Create a free resource that would appeal to the people who would buy your paid product
3. Run Facebook ads to give your free thing away in exchange for an email address (Paid advertising is optional — you could do organic marketing instead, but paying for the leads provides speed you generally can’t get from organic marketing)
4. Sell your product through daily emails

This is a broad overview, but I hope it helps stir up some ideas for you!
