I just managed to spell "vehicles" in an email so badly, vim suggested I might have meant "testicles". I am glad I spellcheck automatically before sending mail to customers.

I'm glad you send your email in vim! I currently don't have that luxury

despite being an emacs chap, I have used vim for email for decades now

Sadly I now work at a place that uses (the horror) outlook web app, sans IMAP access
