Don’t tell me to think before printing your email.
Firstly, it’s not that special. You’re lucky if I’m reading it at all. Do you really think I want a copy for posterity? Am I going to have it framed? Let’s face it, your target audience is pre-Internet execs who have their secretaries print their emails out so they can dictate a reply back later.
Secondly, do you think your sanctimonious footer comes at no cost? Using the power of randomly Googling facts each bit takes 4.6µJ and 2.8 million emails are sent every second. Assuming a 60 character nag if everyone indulged that’s over 12kW of smugness. For approximately no pages of paper saved.
And don’t get me started on lawyers. We could probably stop global warming if they’d just skip the fifteen page footer explaining how it’s somehow your fault if they send their emails to the wrong address.
