“We are all bombarded with too much email. Therefore, we are all very quickly scanning emails to decide if we should take the time to read them. We do this scan by reviewing the from, the subject line and/or quickly glancing at the body of the email.
If a message is not from someone we recognize, we need even more reason to feel compelled to take the risk and open it. We just don’t have time and we are much more likely to not open an unrecognized email.”
