I use https://blogtrottr.com/ https://blogtrottr.com/ to get RSS feeds to my email. I then filter them into a folder and now I have a cross-platform synced RSS reader. I can also do any sort of filtering that I want with email filters. The only real downside is that I haven't found a mail client that will pre-download images in the items. But I can read the text offline at least.
