The Quiet Cost of One Hostile Email

I woke up in the UK, five hours ahead of the US, opened my laptop, and read an email that made the floor drop out from under me. It had gone to a group I am part of, a volunteer organization, and it was aimed at me. For the next several hours, while the people who would read it next were still asleep, I sat with it alone.

This is a more personal piece than I usually write. I went back and forth on whether to share it, and decided to because the pattern underneath it is one I see constantly inside client teams and leadership groups, and because these blind spots stay invisible until someone names them. There is real pain on both sides of what I am about to describe.

Why couldn’t I just let it go?

Here is what I noticed in those hours. I read the email again and again, and every time it only confirmed what I already felt. I could not reach the perspective that would have helped me. That is not a failure of character. It is how the brain works under threat. A trigger sets off a stress response, and the psychologist Paul Ekman named what comes next: the refractory period. It is an elongated stress response, a state in which the brain replays the story on a loop, and each replay releases another wave of stress chemicals. That loop does harm in both directions, to the person caught inside it and to everyone within reach of the stress reaction it produces. Inside that state, you are not seeing the situation. You are seeing the version your nervous system keeps selecting for you.

Why does everyone go quiet?

That same filter was running in everyone connected to the email, not only me.

The person who sent it was almost certainly not feeling cruel. She was, I would guess, carrying an older grievance, a sense of having been wronged that had never been resolved. A grievance held long enough becomes a refractory period that never closes. From inside it, the email would not have felt like an attack. It would have felt like setting the record straight.

I was the target, and my filter handed me a thought I believed completely: this is how everyone sees me. I had no evidence for it. My narrowed brain offered it as fact anyway.

And the people who received it went quiet. Not because they did not care. Their threat systems flared too, and the safest move a nervous system knows is to step back and say nothing. That silence is not neutral. To me it read as agreement. To the sender it read as permission. Silence rewards whoever is loudest in the room.

We are all, at different moments, in each of those three seats.

What does the silence cost?

The cost of all this is easy to underestimate. The damage of a hostile message is rarely contained to the person it targets. It reaches everyone who witnessed it. Under that kind of stress the threat-detection system takes over to protect them, usually well below the level of conscious choice. Some simply go quiet. Others freeze, unable to find words for what they feel. Either way, they step back, contributing a little less and holding their real thinking closer. That withdrawal is rarely temporary, because once a nervous system has learned that a room is unsafe, it does not relax on its own. One hostile exchange can set off consequences that outlast any memory of the message itself, and a group can be left noticeably less stable than the incident alone would seem to explain. The message took minutes to send. The disengagement it leaves behind can take far longer to undo, if it is undone at all.

What broke the silence?

Then the US woke up. One person read the email and wrote to me privately to say she was shocked, and embarrassed to have received it. One message, and the isolation broke. More than that, it allowed my prefrontal cortex to come back online and to realize that the story I had been telling myself for hours was not true. The silence had never meant agreement. It meant other people were managing their own threat response. If you have ever wondered whether reaching out one to one is worth it, that email is my answer.

What made the difference?

My first instinct had been to reply immediately, in kind. I did not, and not because I am unusually disciplined. I have spent years learning this work, and the email still landed hard.

Two deliberate steps helped. First, I regulated, using a simple breathing and refocusing practice to settle my body, because you cannot think your way out of a threat response that is still running. With my prefrontal cortex back online, I broadened my perspective. I made myself ask the questions a narrowed brain will not ask on its own. What am I not seeing? What would I tell someone else sitting where I am? I also put the email in front of a neutral outside perspective, an AI tool, and asked what it saw and how I might respond in a way that moved things forward. A trusted colleague or a night of sleep does the same job – provides space for objective thinking or a new perspective. The point was not to be told what to do, but to import the perspective my own brain had filtered out, so the response I sent was chosen and intentional rather than fired reactively.

So why isn’t awareness enough?

You might think the answer here is more emotional intelligence. It is not, at least not in the way we usually mean it. Most people in that email chain could have defined emotional intelligence well. Knowing the concept did not change what their nervous systems did under pressure. You cannot watch your way to a steady nervous system any more than you can watch your way to physical fitness. Awareness is the starting line, not the finish.

What I would ask you to sit with

You cannot change a pattern you cannot see. The work is learning to notice the narrowing while you are still inside it, so you can pause, recalibrate, and respond on purpose. These are capabilities, not fixed traits, and they can be built. That matters most for anyone who holds authority, because when the person whose vision has narrowed is the one making decisions, the whole group inherits the tunnel.

I am at peace with how I responded. Not because I handled it perfectly, but because I chose my response rather than reacting emotionally on instinct.

So, I will leave you with the questions I had to ask myself:

Are you inside an open refractory period right now, and if so, what story is your brain replaying, and through what lens is it making you see?  What "facts" is it telling you that might not be true?

And could you be the subject of someone else’s, with a person somewhere quietly replaying a story about you that you have never had the chance to hear?

One last thing.

Widening your perspective to consider how things look from someone else’s seat is worth doing.

But the story another person is telling themselves about you is not your business. You do not need to carry it, and you do not need to spend your hours ruminating on it. Let it go.

At Newgrange, building the capacity to stay clear under pressure is the work we do with leaders and teams. If that is a conversation worth having, I am always glad to have it.
