> One question I have to more experienced Emacs users: Can you recommend an email client?
Contrary opinion from an experienced Emacs user (parts of my init.el are older than many users in this forum): I used to be a fan of Gnus, but then noticed that dragging attachments into E-mails is such a productivity booster than I switched to Mail and haven't looked back. If you are on a Mac, the combination of seamless drag&drop everywhere, Mail.app and LaunchBar simply does not compare to what you get inside of Emacs.
I do feel some regret, because I liked the customizability, but facts speak for themselves: I do things much faster with Mail.app.
Interesting. One of the reasons I switched to mutt (well, neomutt) is that it is faster for me to work with attachements from a cli. This is mostly due to tab completion, which for commonly accessed locations is practically muscle memory. Takes me forever to to click my way there.
I often don't even know what the filenames are for my attachments, or where they are in the filesystem. Some are ephemeral.
I'm guessing you haven't worked with MacOS? Most people coming from a Linux/UNIX backgroupd (I was one of them) tend to assume that MacOS doesn't offer much, especially for advanced users, which isn't true. You can do many things significantly faster on MacOS.
In my case, I drag/drop attachments from other applications, from the filesystem, or from LaunchBar (finding things in LaunchBar is way faster than manually navigating through an entire path using tab completion).
