European users will receive spams for a whole day, and the volumes in various time periods are relatively stable.

Worldwidely, the junk emails are less active on weekends. Generally speaking, Sunday has the lowest level of spams. For Asia-Pacific region, the number on the weekends will drop by about 18% than on the weekdays.
