This sounds like a valuable resource, and there's a lot of good stuff on this page: simple call to action, clear understanding of my needs (get first 100 users), and proof that you're using a service that I trust (CovertKit) to send the emails.
Here's why I didn't sign up:
1. I have no idea who is offering this newsletter and what their accomplishments and qualifications are.
2. I have no way to gauge the format and value of the information I'll be receiving.
Fortunately, these are pretty easy to fix: all you need is a photo and short paragraph about yourself (with links to projects that give your advice credibility) and a couple of links to example emails for users to read before committing to signing up.
