There really is no appropriate use of an emoticon in the business e-mail setting because it's hard to understand emoticons of this magnitude. I don't know if the smiley face is a true smiley face indicating you're happy, or if it's a sinister smiley face like 'I'm really not happy because of attitude'. And so it's tough to interpret emoticons in business e-mails and there really are no emotions. It's really depends on the receiver's disposition of whether they are happy that day or sad on how they interpret it, depending upon what emoticons you use in your business e-mail.
