Does writing a letter you never send actually help?

Why a letter to nobody works

Conversations rehearsed in your head tend to go in circles because they have no shape. A letter gives them one. Writing "Dear Sam" at the top points every sentence at one person, which pulls you away from a general mood and toward the particular thing you would say.

Removing the reader matters just as much. When the letter will never be sent, you can write the unfair version, the petty detail and the line you would never say aloud, and only then find out which parts you believe. Studies of expressive writing, where people write privately and without holding back about something affecting them, have found modest benefits on average.

Three everyday letters worth writing

The conversation you cannot have. A former manager you never told why you left, a friend you drifted from without a falling-out, a teammate who took credit for your idea. These conversations are over, awkward or not worth the cost, but they still take up room in your head.

The thank-you. A teacher, an old coach, the colleague who covered for you in your first month. Thank-you letters are often the easiest to write, and the ones most worth thinking about sending.

The disagreement. An argument with a sibling about a family plan, a comment from a friend that stung, a decision at work you think was wrong. Writing it out separates what was said from what you heard, and they are often not the same.

How to write one

Write the first draft fast and without editing. Use the person's name and "you", and include specifics: when it happened, the words you remember, what you did afterwards. A vague letter leaves the feeling vague too.

For a disagreement, a useful frame is four lines you expand as needed: what happened, what I heard, what I think you meant, what I wish I had said. The gap between the second and third lines is often where the whole argument lives.

Stop when the energy runs out, not when the letter feels finished. It does not need an ending, because nobody will read the last line but you.

Read it again the next day

Leave it overnight, then reread it once. Underline the one sentence that still feels true now the heat has gone. It is usually shorter and calmer than the rest of the letter, and it is the real message.

Then try one more step: write the reply you imagine the other person sending. If you can only make them sound cruel or foolish, you have found an assumption worth checking. If their reply comes out fairer than you expected, that is worth knowing before you ever speak to them.

Should you ever send it?

Never send the first draft. If something should reach the person, write a new version built from the underlined sentence, keep it short, and wait another day. Often the better move is a conversation, with the letter as your notes.

Thank-you letters deserve a second look. In a 2018 study, the psychologists Amit Kumar and Nicholas Epley found that people writing gratitude letters underestimated how surprised and pleased the recipients would be, and overestimated how awkward the recipients would feel. Your reasons for keeping a thank-you to yourself may be weaker than they seem.

For a disagreement, ask one question before sending anything: what do I want to happen after they read it? If the honest answer is that they feel bad, keep it unsent.

Keep it where it cannot be sent by accident

Never draft an unsent letter in an email or chat with the person's name already in the recipient field. One wrong tap and it is no longer unsent. Use a notebook, a notes app or a document with no recipient at all.

Then decide what happens to it. Some people tear it up and find that a satisfying end; others keep it to see later how much has changed. Either is fine, as long as it is not left where the person, or someone who knows them, could come across it.
