Question regarding ponctuation

Question

The first two sentences have similar structure, a salutation followed by a question or a declaration.   However, the first uses an exclamation followed by a question; whereas, the second uses a comma after the salutation and then continues making it all one sentence,   If you use the first sentence's pattern, i.e. using an exclamation instead of a comma, this is marked wrong.  Please explain, as this is a recurring issue..  Thanks

Bonjour Frank,
Thank you for your comment! I will make sure to pass it on to our French team. In the meantime, take a look at a similar question: Missing or erroneous punctuation.
Also, it is best to concentrate on the actual language content rather than the punctuation as it can differ from English, for instance, there is a space before an exclamation and question marks in French but not in English.
EDIT: we have now accepted "Bonjour Annie !"
I hope this is helpful.
Bonne journée !
