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.

The other replies are interesting as it sounds like the bar for entry (at least from HN people) to giving up an email address (even a disposable one!) is pretty high.

Anyway I signed up - I know I can unsubscribe if I don't like it, and I very much doubt you are a spammer (which I define as someone who won't let me unsubscribe!)

It's probably worth outlining what we are going to get in bullet points, and a bit about your experience though. But hold on, I don't need to tell you that!

Good luck. I recommend sharing your story on Indiehackers.com. Marketing newsletters seem to go down well there.

How do I know the content creator knows anything about marketing? In fact, the presentation of this (and lack of sales copy, testimonials, previews) makes me wary of getting information from this resource.
