You are writing to Julia Smith. You haven't met her before, what would be the best opening?
Dear Ms. Smith
What is a more formal word for "help"? (noun or verb)
assistance / assist
Why is "Hello" be a bad subject line?
It doesn't explain the reason you are writing or who you are. Also, a more specific subject line makes sure that the message isn't mistaken for spam, or simply ignored.
