Email Knowledge

What do we really know about email and the way we send things? I have learned many things. When sending emails, especially when having conversations through them, I know to be very cautious about things that you send. I feel like I have learned a lot. When receiving email, I know to read whose emails are in the CC: field if any. And because you can't see who is in the Bcc: field, just to be careful. No matter if your being rude, which you shouldn't, or sharing personal information.
