He’s so right. Email is too valuable a communications tool for it to be strangled by spam and thoughless overuse. I endorse his advice to outlaw group copying or ‘reply to all’.
Here’s a question. What proportion of your organisation’s emails are internal, and what proportion external? Freelancers have a perfect business model in that 100% of messages must be external. But for most middle managers in large organisations, internal messages represent, I suspect, the vast majority. It’s similar within a university, though if I define students as external on the grounds that they are equivalent to customers, I find to my pleasant surprise that 87% of my inbox is from external correspondents. Perhaps I’m simply quicker to delete my colleagues’ messages. What’s in your inbox?
