Idk, a working basic email client is just not that hard to write though. SMTP and IMAP are simple protocols and the required graphical interface is a very straightforward combination of standard widgets.
I don't mean to be contrarian, but this is completely false.
IMAP _seems_ to be a straightforward (but nasty and stateful) protocol, until you find out that every major provider ignores RFCs and does things slightly differently.

It's a hellscape.
