Reeder app, especially now that it comes with a decent iCloud sync and a free Read Later service. The one time pricing is very stressfree, not to mention their polished UX making for a very pleasant experience. If you're comfortable on an Apple platform there's Reeder for desktop and iOS and they're all solid. I do miss a feature or two from Feedly, but in general am a very satisfied convert.
Funny enough, it has the exact opposite feature of this submission and I love it. Email newsletters via rss reader.
I use email basically as a todo list, so emails that aren't very important (e.g. newsletters) get pushed out of my inbox quickly. This always have me an uneasy feeling, as I frequently felt rushed to read newsletters when I got them, which I never loved.
Now I can just check newsblur every few days/once a week, and I can read newsletters and whatever else when I'm in the mood!
I am currently not set up to read RSS feeds, but I want to set up Newsboat [1] for a machine connected to a real VT terminal and RSSMii [2] for my Wii connected to my tv.
