US adults have both personal and work email accounts

More than half of working adults (53%) have both personal and work email accounts. And while 22% say they only maintain personal addresses, just 5% say that their email use is limited to a work account (of course this is what they will say).

54% of employees with personal email accounts say they at least occasionally check their personal inboxes while at work and most do so on a daily basis. Personal email spills over to the cell phone and Blackberry, too: Among employed respondents who actively use their cell phone or Blackberry for email, 44% say that most or all of the messages they send and receive are personal, while 32% say that most or all of the messages are work-related.

Another 25% say their email use is equally split between personal and work-related messages. 37% of those with work email accounts check them constantly, up from 22% in 2002, according to Pew Internet Project.
