To write a gratitude letter, name one person, describe one specific thing they did, and say what it changed for you, in about 300 words. Most people can do it in one sitting. Below is a fill-in template, a full example letter, advice on whether to send it, read it aloud or keep it, and what research found about how much these letters mean to the person who gets one.
What is a gratitude letter?
A gratitude letter thanks one person for one thing they did, with enough detail that they can see exactly what it meant to you. It is longer and more personal than a thank-you note for a gift, and it is usually about something that happened a while ago and was never properly thanked.
The idea comes from positive psychology. In a 2005 study, Martin Seligman and colleagues asked people to write a letter like this and deliver it in person, an exercise they called the gratitude visit. It has been one of the best known exercises in the field since.
How do you write a gratitude letter, step by step?
Five steps, in this order:
- Pick one person: someone who did something that mattered and never heard it from you. Living and reachable is easiest, but not required.
- Pick one moment. Not "you were always there for me" but the afternoon, the phone call, the decision. Write down where you were and what was said.
- Say what it changed. What did you do afterwards that you would not have done otherwise?
- Say where it shows up now: a habit, a job, a way you treat other people that started there.
- Close simply. Thank them in one plain line. You do not need to ask for anything or promise to visit.
How long should a gratitude letter be?
About 300 words, which is roughly one handwritten page. Shorter letters tend to slide into general praise, and much longer ones start to read like a speech.
Spend your words on details, not adjectives. The date, the place and the exact sentence they said do more than "amazing" or "incredible", for the same reason specific appreciation lands harder than general praise.
What should a gratitude letter include? A template
Fill each part with one or two sentences of your own. The example lines are from a letter to a former teacher.
| Part | What to write | Example line |
|---|---|---|
| Opening | Who you are writing to, and why now | Dear Ms. Okafor, I have meant to write this for eleven years. |
| The moment | One specific thing they did, with a detail | In my last year of school you kept me after class to say my essay about my grandfather was the best thing I had written. |
| What it changed | What you did because of it | I applied to study history because of that conversation, which I had not planned to do. |
| Where it shows now | How it is still part of your life | I teach now, and I keep students back after class for the same reason you kept me. |
| What you noticed about them | A quality, shown through what they did | You did not have to do that. You had thirty other essays to mark that night. |
| Closing | Thank them plainly | Thank you. It mattered more than you could have known. |
What does a good gratitude letter look like? An example
Here is a full letter of about 200 words to a friend, following the same six parts.
Dear Sam, there is something I never properly thanked you for, and I would like to now.
Four years ago, the week after I lost my job, you drove two hours on a Saturday to help me clear out my apartment. I had told everyone I was fine. You came anyway, with two coffees and a roll of trash bags, and you did not ask a single question about work until I brought it up myself.
Sitting on the floor between the boxes, you asked what I would do if money were not the problem. I said I would cook. You said, "Then find out what it takes." I looked it up that night, and I started a culinary course the next spring.
I run a small catering business now. Every time I take on someone who is between jobs, I think of you on that floor with your coffee going cold.
You have a way of turning up before people ask, and of never making a fuss about it. I noticed, even when I did not say so.
Thank you, Sam. For that Saturday, and for the question. Love, Jordan
Who should you write a gratitude letter to?
Anyone who did something that mattered and never heard what it meant to you. Some places to start:
- A teacher, coach or manager who saw something in you early.
- A friend who showed up during a bad stretch.
- A parent or grandparent, about one specific thing rather than everything.
- A colleague whose quiet help made a hard project possible.
- Someone you have lost touch with. A letter is a gentle way back in.
- Someone who has died. You can still write it, then read it aloud somewhere that matters to you, or keep it. If it stays heavy, or you think of harming yourself, findahelpline.com lists free help.
Should you send a gratitude letter, read it aloud or keep it?
Each option does something different, and all of them count.
If you are unsure, send it. What researchers found about how recipients feel points that way.
- Read it aloud in person. This is the original gratitude visit: tell them you have something to read, read it slowly, then leave room to talk. It feels the most awkward beforehand and is often the most moving.
- Send it by mail or email if you cannot visit. A handwritten letter is something they can keep and reread.
- Keep it if the person has died, if contact would not be safe or welcome, or if you are not ready. The writer still benefits: the letter-writing studies below measured the authors.
Will a gratitude letter feel awkward to the person who gets it?
Probably much less than you expect. In a 2018 paper in Psychological Science, Amit Kumar and Nicholas Epley ran three experiments in which people wrote gratitude letters and predicted how the recipient would feel. The recipients then reported how they actually felt.
The writers underestimated how surprised recipients would be by what they were thanked for, and underestimated how positive recipients would feel. They also overestimated how awkward recipients would feel. Writers who expected more awkwardness were less willing to express gratitude, which is how good letters end up staying in drawers.
Does writing a gratitude letter make you happier?
For many people, yes, at least for a while. In Seligman and colleagues' 2005 study with 411 participants, the gratitude visit produced the biggest short-term rise in happiness and drop in depressive symptoms of the exercises tested. The boost lasted about a month, and by the three-month follow-up it was gone.
Writing more than one seems to help. In a 2012 study by Steven Toepfer, Kelly Cichy and Patti Peters, 219 people wrote three gratitude letters over three weeks. Their happiness and life satisfaction went up, and their depressive symptoms went down.
This matches what research says about whether gratitude journaling actually works: the effects are real but modest, and they fade if you stop. A letter is not a treatment for depression. If you want more than a short lift, write another one in a few months.
How do you write a gratitude letter to yourself?
A gratitude letter to yourself thanks a past version of you for something specific: a hard decision, a habit you kept up, a time you asked for help. Use the same template, written to "you" at a particular age or moment.
Keep it concrete. "Thank you for being strong" is too vague to believe when you reread it. "Thank you for calling the doctor in March when you wanted to ignore it" is the kind of line that holds up.
What if you do not know what to write?
For shorter daily prompts about people and ordinary days, the gratitude journal prompts that go past family and health work the same way and make good raw material for a letter later.
Use one of these prompts to find the person and the moment, then go back to the template:
- Who taught me something I use every week?
- Who said one sentence to me that I still remember?
- Who took a chance on me before I had proved anything?
- Who was kind to me when they had no reason to be?
- Whose small habit did I end up copying?
- Who made a hard week easier, and how exactly?
