Composing an out-of-office message used to take 30 seconds and was usually written minutes before you headed to the airport on vacation. As a friend’s OOO noted: “I am offline until Sept. 29. Off the grid. No email. No phone. No texts.”

In a very few words, this sent a big, clear message.

Now, out-of-office emails have become Rorschach Tests for our relationship to our inbox, our friends and ourselves. True, fewer of us have an office to be out of anymore. But email, far from being dead, is gobbling up the world. We now send and receive 361 billion emails every day.

My first clue that emailing was becoming a platform for pearl-clutchers and virtue-signalers came last year when I read on the bottom of a friend’s email: “I am sending this email at a time that works for me. I don’t expect you to respond to it until normal business hours, or when it suits your own work-life balance. I encourage you to make guiltless work-life choices and support flexible working.”
