My most satisfying email was when some project manager at the business partner company asked me why I wasn’t in a teams meeting to let their team test their software on our machine. This was an email basically everyone in both companies was on. My boss, his boss, that guy’s boss, all the way up the ceo, and her boss and her boss’ boss, etc.

I replied all with screenshots and an email that basically read “hey, you kicked me out of this meeting now twice. I can’t be there if I’ve been removed”.

I got an email back a minute later where she only replied to me with a sheepish “no i didn’t”
