Email Marketing - How to Get More Signups From Your Email List

Amazon doesn't share customer data. So the only way you can gather data is to offer some sort of a freebie where you say, Hey, thanks for buying my book. And then when they sign up using their email address, you send them that free complimentary product. I do this with every single book because it's just a great way, again, to gather emails from from your readers and then start building a connection with them.
