Being smarter about how I read my mail. Less-awful-UX in email clients.
This problem is not too hard to solve on Windows or Macos. On linux it is a shitshow. Consequently, I have listed all the linux-specific options separately. You could probably have a look at those too. Many of them run on Windows or macos too. (Although the ones that do are uninspiring).
Apple Mail is built in to macos and I think it is pretty good. Obviously only runs on macos.
gpgtools will upgrade even Apple Mail to be a bit more encryptey, if that seems exciting.
Mailbird (Commercial, Mac/Windows).
Polymail (Commercial, mac/windows/ios/maybe android) is an email client that promises AI automation stuff.
Spark is a commercial app that comes recommended as being less of a mess than other mail thingies and for innovating in design and such. (macOS/android).
Postbox (macos/windows) seems OK. USD29.
eM Client Mac/windows. AUD80
