How to Write a Good News Letter for Your Book?

The one marketing thing that i find has remained consistently valuable for me is the news letter. A series with engaging characters is the one way to, sort of the best thing you can do as a writer. It gets people really into interest in your stuff, and they'll follow you as an author if you really develop your voice in that way. I'm thankful for the internet because it's changed how we market our books over the last ten years.
