You’re as likely to lose an email as the checked bag on your next flight More email is lost than I thought. The loss rate is at least 0.7%, or 7 messages in 1,000 . If you send ten messages a day, this means 25 will go astray in a year. For comparison, airlines operate with 3 to 10 lost baggage reports per 1,000 passengers on major airlines . As for the old-fashioned way of doing it: the British Royal Mail has admitted that more than 14 million letters and parcels were lost, stolen, damaged or tampered in 2005, out of 22 billion items handled. That’s 0.06% — ten times better than email!
