Answer 1

Answer:

Many times, student start emails with “Hey” or no greeting at all. Always start with a greeting; this is friendly and courteous to the recipient. For example, start with “Dear Mr. Gonzalez” or “Hi Ms. Smith.” If you have never met the instructor or teacher before (maybe you’re trying to get into a full class or switch sections), always start with “Dear,” as this is more formal.

Dear [Name],

Hi [Name],

Good morning [Name],

Good evening [Name
