gmail IMAP can be excruciatingly slow. One mitigation is to set
gmailʼs imap folder size limit to something less than infinity (I use
1000). But I donʼt fetch from gmail to local, I leave everything on
googleʼs servers.

I think thereʼs been some work in this area in emacs-29 and/or emacs
master to make the code more robust. You could try using emacsʼs
direct SMTP support, but that might not be a small change in your
setup.
