Spare us the e-mail yada-yada

“IF THIS e-mail is received in error, notify the sender immediately.” “This e-mail does not create an attorney-client relationship.” “Any tax advice in this e-mail is not intended to be used for the purpose of avoiding penalties under the Internal Revenue Code.” Many firms—The Economist included—automatically append these sorts of disclaimers to every message sent from their e-mail servers, no matter how brief and trivial the message itself might be.

E-mail disclaimers are one of the minor nuisances of modern office life, along with fire drills, annual appraisals and colleagues who keep sneezing loudly. Just think of all the extra waste paper generated when messages containing such waffle are printed. They are assumed to be a wise precaution. But they are mostly, legally speaking, pointless. Lawyers and experts on internet policy say no court case has ever turned on the presence or absence of such an automatic e-mail footer in America, the most litigious of rich countries.
