alt Hacker Newsno mention of rss via email?
https://github.com/rss2email/rss2email https://pypi.org/project/rss2email/
i have been using this for 20 years already. by now my own version has accumulated a few custom patches. but the original it is still under active development/support. some day i need to submit my changes upstream.
I have my own custom perl script which basically does the same which I've been using for probably a similar amount of time. Never used a dedicated RSS reader. My feeds just get turned into email and dropped into the appropriate folder thanks to my sieve filters. Can read/delete things from any of my email clients. Absolutely no need for a dedicated RSS reader.
