It’s no understatement to say that e-mail has had a profound effect on our professional and personal lives. People thousands of miles away from each other can send and receive detailed documents within mere seconds.This allows us to take on projects that wouldn’t have been practical or possible only a few years ago. It has become routine for us to correspond and exchange files with people overseas. The only obstacle is the difference in time zones.
But on the other hand,e-mail can eat up a substantial portion of our workday. Most of the time and effort involved is going through unsolicited messages and separating the good from the bad. But not all unsolicited messages are spam.
