  1. Business emails: If you're sending an email to a colleague, client, or someone you don't know well, a formal greeting can be a good idea. This shows respect and professionalism.
  2. Formal or official emails: If you're sending an email to a government agency, a university, or a company with a formal tone, a formal greeting is usually expected.
  3. Emails to someone you don't know: If you're sending an email to someone you've never met or don't have a prior relationship with, a formal greeting can be a good way to establish a professional tone.
