First president with regular email access

According to Official Guinness Records,

Among the first few announcements made when Barack Obama (USA) took office in January 2009 was the news that the president, an avid emailer, would use email to stay in touch with senior staff and personal friends during his presidency.
However the title for the first US President to use email in office goes to President Bill Clinton (USA), who sent one e-mail as a test and another, with the help of his staff, to astronaut John Glenn while the astronaut was in orbit on the Space Shuttle.
