Summary: Why is building an email list so important? Well think about it, if someone downloads your freebie and gets on your list...they are taking extra steps from your website/social media to get on your list. They may be downloading a freebie but they know very well that they are getting on your email list. If a follower takes that extra step to get on your list-- I think you can consider them a VERY warm lead. Now it's up to you to nurture that lead to turn it into a sale.
