It is always important to keep a formal formatting when emailing a professional individual or someone that holds a higher title than you. When you sound informal or have misspelling in your email, they might not take you seriously. For example, when emailing your college professor it is good to keep in mind the proper formatting before sending that email. You would want to mention your name and student ID if needed as well as what class/section you are in. With hundreds of students, you can get lost in those emails. At the end you should thank them for reading your email and let them know you are understanding of any situation.
