The golden rule for email management, according to Weiner, is, if you want less email, send less email.
He writes on LinkedIn that the rule occurred to him at a previous company when, after two email-happy colleagues left the company, his inbox traffic decreased by almost 30%.
"Turns out, it wasn't just their emails that were generating all of that inbox activity — it was my responses to their emails, the responses of the people who were added to those threads, the responses of the people those people subsequently copied, and so on," Weiner writes.
He continues: "After recognizing this dynamic, I decided to conduct an experiment where I wouldn't write an email unless absolutely necessary. End result: Materially fewer emails and a far more navigable inbox. I've tried to stick to the same rule ever since."
