So, I need to write a letter to the HR Manager at work but i'm not sure how to address it to her.
I know her full name (but not title... E.g. Mrs/miss) but i have never spoken to her so am not exactly on first name terms.
Would i be best to address it
1. Dear Jane
2. Dear Jane Smith
3. Dear Ms Smith (Ms is what you use when you don't know the person's title, isn't it?)
Or am i better off just Dear Madam?
