Now that you have a list of words not to use, take a moment to consider how to construct an effective subject. The best rule of thumb is to simply say what you mean in a subject line. All too often, email subjects are overly vague and meaningless. If your email is important, place a snippet of its importance in the email subject line. If you are trying to reach customers, use the subject line to begin the sale. Don’t hide your pitch or use the subject line to try to trick your recipients! Be direct and be relevant.
