When I am writing emails, I prefer to use either Mr., Mrs., or Ms. when addressing the recipient's name. When I am addressing a woman, I may not always know their martial status and don't know whether to use "Mrs." or "Ms."

Assuming I have no way of knowing this person's marital status, should I use "Mrs." or "Ms."? Or is it best practice to use neither?
