How do I punctuate a greeting like “Hi, Anne” in an e-mail or other message?
How you punctuate an e-mail or other greeting depends on the level of formality and the structure of the message. In a formal message, one that does not begin with a direct address, you would likely write:
But the greeting “Hi” is a form of direct address, which by convention is set off with commas:
That said, “Hi” marks the correspondence as informal. Thus, you might omit the punctuation:
If you run the body of your correspondence into the greeting line, as in a text message, you might use a period instead of a comma after the name:
Hi Anne. Do U want to meet l8ter?
