Another way to get out of an email thread is simply to ask to be removed.
"It sucks when you're stuck on an email thread of declining relevance," writes office culture expert Jocelyn K. Glei in "Unsubscribe: How to kill email anxiety, avoid distractions, and get real work done."
Glei offers a graceful way of escaping a thread by saying this: "Looks like you guys have taken the reins on this conversation! Would you mind moving me to 'bcc' so that I can bow out?"
If the chain isn't work-related, however, Glei gives a more personal example to keep things amiable: "Sean — Would you mind moving me to 'bcc' when you respond? I'm waging war on inbox clutter this week. ;)"
Whatever you do, don't ask to be removed from an email thread via "reply all."
You may end up in a hellish echo chamber with a million people asking to be let out, like NHS employees were in 2016. The UK health service's 1.2 million employees received a "test" email, which caused some of them to hit "reply all," asking to be taken off the recipient list. Since a single email in the thread reaches 1.2 million accounts, NHS's servers slowed down considerably when dozens of annoyed employees sent a collective 140 million emails.
The same thing happened to 11,543 Microsoft employees last January, when an employee reportedly sent out a message to the entire company explaining how to change their GitHub accounts to get fewer notifications.
The irony was not lost on employees, one of whom described the fiasco as a "reply allpocalypse." The moral of the story: don't, under any circumstances, hit "reply all" to thousands of people.
