I use Newsblur, mostly. It feels a bit dated at times, but does what I want it to do and has an email address that you can send newsletters to to read like feeds. I've been meaning to switch over to miniflux for a while, but can never really get up the momentum. It seems nice.
NewsBlur - I'm on a paid plan since I'm a packrat with almost 700 feeds. It is a pretty busy interface but has tons of functionality. Their mobile app is also pretty good.
I use an RSS-to-email service to email them to me. Then most feeds get sorted into folders for reading later. A few got to my inbox for more urgent response.
I currently use an RSS-to-email service that I operate but I used other services for almost a decade before that. There are a handful available ad supported and paid or you can self-host.
I moved all my stuff to Thunderbird a while ago, and unless you have more specific demands, having a basic self-run RSS reader beats just about all fancy hosted solutions out there. Old-school e-mail works well a lot of the time too.
I know NetNewsWire and NewsBlur have already been mentioned, but I use both of them together. I use NewsBlur on Windows, and NetNewsWire with my NewsBlur account on Mac/iOS. NetNewsWire also supports iCloud, Feedbin, Feedly, and other services (and locally without syncing).
