Here’s a chart of how many email messages I’ve sent and received since 1995 at my day job. These numbers don’t include spam, or messages that I’ve deleted. It looks like email as an office tool really started to take off in 1999. I’m not sure how to explain the variations in received mail between 2004 and 2006. Regardless, it looks like I can’t type any faster than about 2500 messages a year...
