I have a book that's going to be showcased on a landing page, and I am wondering what's the best way to collect an email before sending the site visitor to buy the book on Amazon. I have a few options, tell me what you guys think: 1. Have an email sign up welcome mat from SumoMe at the top on the landing page 2. Have a normal email optin form and have a pdf of the first two chapter of the book with an aff link at the bottom (not crazy about reprinting parts of the book in a pdf to float around the internet) 3. Use Leadlocapp to get the email after they start reading (in order to continue reading) I am not trying to inhibit sales of the book, but at the same time I hate wasting an opportunity to gather an email. Just wondering what everyone here does. Thank you for your replies..
