I pretty much have this setup currently:

Email hosted by a 3rd party (like migadu or purelymail) then moved my cell number over to voip.ms, which sends all texts and voicemails to me via email, where I can now respond to texts via my email client. Then I use feedmail to have all my rss and social feeds email the full text and images to me in either a digest or when they are published.

I have to say I've been loving it. I'm currently setting up notmuch and alot as my mail indexer/sorter and commandline viewer, too.
