In an email, the (B) subject line should be brief, but highly descriptive. The subject line is the line that captures what the email is about and in most cases, determines whether or not the reader will open it. This is why it is important to be descriptive, but not that long. The emoticons have nothing to do with the email content and the bcc is a type of email reply/send option. The domain also has nothing to do with the email subject and content.
In the Subject aswell as the conclusion of the email this includes shortening the Subject of the email but letting the reader grasp the intelligence in the subject. In the conclusion of the email be shrot but use intelligent words that would present yourself as a worthy intelligent indivisual.
