Thanks! Is the exclamation mark added even when considering only grammar and not emotions?
Answered by Writeacher
The reasons for using the exclamation mark are especially well stated in the linked webpage above.

You'll need to give me some examples for the rest of your question: "... even when considering only grammar..."

Well, suppose I say, "How nice it is?" Would that sentence be termed as grammatically incorrect?

Simply because the sentence begins with an interrogative word doesn't mean it's a question. A question mark there is an error.

Ask yourself ... is this truly a question? Or is it a remark about beautiful weather or a wonderful party? Or?

Grammatically, this is not a question. It's a remark that needs an exclamation mark at the end.
