Every time we open email, we're looking at communication that can drive business to our firm. Whether the email is from a vendor, customer, or colleague, we likely act quickly to respond and follow-through. Since we may often get emails from the same address or contact, we may sometimes act too quickly when we reply to an email. We may not notice that the email is, in fact, not from whom we think. Such a message may ask us for payment details, password credentials, or other seemingly innocent and important details what we'd typically jump right on. The desire to reply quickly can open the opportunity for headaches.
