E-mail glut costs business. The London Free Press. July 31, 2004.

Report on a recent survey by Christina Cavanagh, professor at Richard Ivey School of Business at the University of Western Ontario, in which we learn that the average corporate information worker is spending approximately one hour more (over last year) to deal with an overloaded workload. Business users average receiving 54 e-mails a day, not including SPAM. This represents an increase of 13% over the past year. More recent statistics estimate that figure at 64 e-mails a day.
