After reviewing over 30 landing pages on the Newsletter Creators Facebook Group and Signing up for 10 newsletters with 0 subscribers, I found out the most important word in your description.
The best format for a one-liner is:
what you do for who you do it for
It's probably best to steer clear of "my writing" or "my musings" unless you're only going for your own existing audience for subscribers.
Terms like "News" should have some kind of qualifier word. What kind of news can you provide me that I can't get anywhere else?
It's confusing to have more than 2 - Whos. If you can have one group, great.
Be as specific and broad as you can.
Write as the group you're writing for identifies themselves. Adverbs hurt more than they help.
A one-week feature took two months, mostly spent keeping three systems in sync
I like your observations on newsletters. This is not the first time I read something very useful. You have my respect on this topic.
Thanks for this, I need to "find my for" for my recent newsletter.

+1 on this advice. When I was writing my book, I called it "Technical Content Development Handbook." While revising, I changed the title to "Writing for Software Developers" which makes the value prop very very clear for exactly the reasons you explain.
Quickly checking my landing page..... and sort of have it covered. But I do like the simplicity of that formula and will play around with my heading / subheading
