Email Activity Random But Cyclical

Looking at aggregate data of 3,000 email accounts over a three month period, researchers at Northwestern University say that emails are responded to randomly, but the volume of sent mail follows predictable patterns. Namely, late at night on the weekends it’s much less likely you’ll receive any reply, for the obvious reasons — sleep and time off from work on weekends. The study suggests that the best time to contact someone when looking for a timely response, such as Monday morning, and can help network administrators plan for high-volume periods. Connectivity at home is better than it was when the data was recorded, but is it just me or do you actively avoid email outside of business hours as well?
