When you're writing formal letters or e-mails, the most common way to start them off is with:
- the word "Dear"
- the title of the person who you're writing to ("Mr." or "Ms.")
- the person's last name
- a comma (",") for less formal letters or a colon (":") for more formal ones
Dear Ms. Yokoyama:
Dear Mr. Traven,
- You're writing to a customer who you don't personally know.
- Your message might involve some legal action.
- You're applying for something like a job or admission to a school.
