How Do I Use Email For Product Validation?

Today's question comes from Nickeya, who has a question about using email for product validation. This is an area I’m very interested in. I mention Chris Ducker's experiences with infomercials, which is very similar to how we can validate products in the online world (http://chrisducker.com/).
