First, there’s the missing comma. “Hi” initiates a direct address, so it should be followed by a comma: “Hi, Everyone!”

Is there a comma after Hello everyone?

Do you put a comma after “hello” in “hello everyone”? Strictly speaking, a comma should be placed after “hello” in “hello, everyone” because the statement is an example of a direct address. In informal conversations, such as in online direct messaging platforms, the comma is often left out or omitted.

Should you put a comma before everyone?

Yes, as a matter of grammar, you need this “vocative comma,” because you are addressing “someone:” a group conceptualized by the indefinite pronoun “everyone.” Thanks, everyone!

The same applies even if the sentence ends after the salutation. In this case, you can say “Good morning, Jim.” or “Good morning, everyone.” If you include another salutation beforehand, include a comma between that salutation and “good morning.” For example, “Hello, good morning.”
