MakerList - five curated articles every week to help you uplevel your business

I like the simplicity and brevity there. It's very up to a point.

Now I am wondering if the content of the newsletter is as high quality as the expectations. Maybe you could link to an example letter?

Nice choice on the bold orange - it helps direct the eyes to the important bits straight away. Some initial observations:

I'd change the heading to be directed at the reader with "your" rather than "their":
"Indie Hackers: level-up your business with five curated articles every week". You get the gist :)

Is there any reason you have a link to the subscription form on the homepage, rather than just including the form itself? Seems like an extra hurdle to grab that signup.

I'd add an example newsletter so people know what they're getting (I stole this pointer from the feedback on my post here: https://www.indiehackers.com/post/gymsushi-a-bite-sized-newsletter-about-fitness-nutrition-4b5987c799).

Nice job!
