5. Not monitoring your email inbox. If your social networking notifications go to an email address you don't check, you could be missing opportunities. Be sure you know where those important messages will land, and if it isn't in email boxes you normally check, make a note to change the email or have them forwarded to an address you monitor closely. 6. Accidentally sending an email to the wrong person. It happens. You use the touchpad on your Smartphone to select an email and reply to it, only to receive an immediate auto reply - from the wrong person! Oops - you realize your phone pulled up the wrong message. If you're lucky, the content you accidentally sent was non-confidential or neutral and a quick note saying you're sorry to have sent a misdirected email takes care of it. But, what if it was an email meant for a friend complaining about your boss - that went to your possible next boss? Can you say "career killer?"
