Also account is connected to Youtube, which means another risk.
Answer
If you are trying to filter out prospects from real leads, then create a new email address for those and when they are real opportunities, that is when you get engaged. Also get off Gmail and to at least some type of hosted exchange. This way you can create shared mailboxes.
