Hi everyone!
I'd like to know how you'd normally punctuate the salutation of an email. I know there are no established rules for this; that's why I'm asking about your own experience.
Which of these are acceptable?
To a friend:
Hi John!
Hi, John!
Hi John,
Hi John.
Hi John:
Hi John
To a company / colleague / manager:
Dear X,
Dear X:
Dear X.
Dear X
Thanks a million!
Mara.
