How many exclamation points are acceptable in a work-related email? Does it depend on how excited!!! you are [pretending to be]? Is it just one, because that’s technically correct? Are they too informal? Can we use any at all?
And what about the quesclamation mark?! Is that even real‽
Or for emphasis (!) or sarcasm (!) ?
When I say “Good afternoon, So-and-so!” I find just one! punctuation mark half-hearted, and none quite rude, while two!! looks odd to me, and I think three!!! may make me seem overly-enthused about the day.
Also, what about ellipses…?
