Ask HN: Do you know any good paid newsletters?

Do you have any links to share for quality fee-based newsletters?

- No advertisements.

- Any subject, language or country can be interesting.

- Paper, email or RSS based.

- Written. No video or audio podcasts.

- Not too much editorialism or buzz, just information.

I have almost completely abandoned the sponsored newspaper press, which only transcribes the ambient psychosis and the big media agencies.

I'm looking for new sources, there's a lot of good stuff in blogs, specialized press and podcasts, but I've recently seen some old-fashioned paid newsletters in the field of economics and I find the model interesting but not widespread outside of economics and societal circles.
