Watch your email headers
"Be clear and concise with your email heading," Michael Kerr, an international business speaker and author of "The Humor Advantage" told Business Insider.
"Your email subject line should make it clear why you are writing and make it easy for the receiver to file and later retrieve the email as needed. And don't forget to change the email heading as needed. If you are engaging in a lengthy back and forth over several days then change the subject line to reflect the new direction the conversation has taken to avoid confusion at a later date."
