This first way may apply to bloggers, but also applies to podcasters as well. I'm talking about creating meaningful, unique content on your show's episodes. Your show has to deliver on strong content that will motivate your listeners to opt in to your email list. This content has to be consistent, unique, and valuable enough to them. When it fulfills all these things, they're going to want more and collecting their emails will allow you to offer more free content or updates that are exclusive to your subscribers.
