The reliability of email is almost entirely dependent on a liberal definition of reliable and the part that isn't dependent on semantics can be entirely explained by random events repeated millions of times. There are only two reasons why email works at all: one, recipients want to receive emails, so they actively search for valid messages and two, senders know the likelihood of their messages being read is highly dependent on using human intelligence to navigate past the automated potholes in the information highway.
In my final year of university I was part of a team doing a marketing study of Telidon, which predated Sir Tim Berners-Lee's World Wide Web by a decade. I wrote that Telidon's success would depend on making large quantities of diverse information available for a fixed rate, but I never imagined what would happen when content that costs nothing to produce blankets the globe like a giant cloud of noise.
