Teaching Students Email Etiquette

Does it drive you crazy when you get an email from a student and they put the whole message in the subject line?  Or they write like they are talking to a friend, " hey can u plz send the hw thx"

Wayground (you know them, they used to be Quizziz), created a quiz game you can use with your students to help them understand what to do.  You can also edit the quiz to better meet the needs of your class or school.
