I can find a lot of reliable information on the American unemployment numbers online (I would not trust those of the last five or so years), can find the number of computers and even the number of commercial email addresses in America. In addition the number of computers (even commercial use ones), and the number of email addresses, e.g. email@example.com addresses with multiple users – are not what I seek. What I wanted to know however is the number of American employees required to use their workplace email address for official business. I suspect the percentage (not the number) is between 99 and 100% of all those who are, or have, ever had an email account tied to their employer. If anyone out there has an employer email and is not required to use it for business I’d like to know and will publish this information (with your approval of course).
