What does HackerNews think of rss2email?
open-source tool for Windows, Mac OS and UNIX for getting news from RSS feeds in email

Which is a "port" of the very old/established python project with the same name:

If you have a server somewhere, you use cron and configure a list of feeds. Each time a new entry appears you get it sent as an email.

Just sends the latest articles to an IMAP folder. I can use any device that syncs to my email (currently using the built in ActiveSync client on Android), and can access it from webmail, and via Thunderbird on Linux.
Why using email? I switch between phones, OSs etc and it was a bitch to find decent clients for the self hosted options on each OS. I can generally get my email everywhere, via ActiveSync on my phone, WebUI, thunderbird etc. And since I host my mail, the data never leaves my network :) It works really well, though I do sometimes feel like RMS having web pages emailed to me lol

I've been using it for a few years and, while the command line interface is a bit awkward, it works fine. Since email clients have the same controls an RSS reader needs (read/unread, folders, etc.) it works fine.
Blogtrottr is a hosted service that does the same thing; I also used them for a few years and was happy with the service. Just moved off because self-hosting was in some ways simpler for me.
Pros: It sends to my Gmail account, separated by labels, and I can read both in PC and mobile.
Cons: you have to run the command in your PC.
