FairEmail. I used to use K9 but FairEmail is far and away the better app. Lots of work ongoing to make it better as well

Checking their website, FairMaail looks promising. Too bad that it's only available for Android.

Agreed. It's fantastic. Happily paid for it and switched to it from K9.

I find Joplin https://joplinapp.org does a good job of producing markdown from web pages and already has sync capability built in. Looks like it would be ideal for working with Obsidian

Exported my Joplin markdown and opened it up in Obsidian. Works like a dream and the best part is Jopli already has it's own web clipper. Seems like a superb match
