Bill Clinton sent only two e-mails throughout his eight years as US
president.

While speaking at a Wired for Change technology conference in 2011,
President Bill Clinton confessed that he sent only two e-mails during his
entire presidency. One e-mail was to the United States troops in the
Adriatic, and the other was to John Glenn for his 77th birthday, while he
was in orbit around the Earth on the shuttle Discovery. E-mail has been a
relatively common form of communication since the early 1990's (the term
"e-mail" being coined around 1993). President Clinton was in office from
1993 to 2001 and the staff of the White House sent around 40 million emails
during this time. These e-mails have been archived in the Bill Clinton
memorial library, along with the two emails sent by President Clinton
himself during the same period.
