Problem: In this chapter we learn about how ebooks are sometimes given away for free if you provide your email address to download the book. After doing so your email is likely loaded into a marketing list that the company will try to sell you something afterwards.
Have you ever provided your email to download a free ebook (or white paper, etc)?
Do you think this is an effective strategy for internet marketing? What types of businesses can most utilize this strategy? Please provide an example of what type of business.
