HOW TO
Write letters to strangers
A stranger is the only reader who meets you exactly as you are on the page. Here is what to write, and where your letter can land.
There is a particular kind of honesty that only comes out when you are writing to someone you have never met. No shared history to protect, no impression to keep up, nobody who will mention it at dinner. Just a page, and a person somewhere who will read it.
If you want to write letters to strangers, this guide covers why it is worth doing, what to actually say, openings you can borrow tonight, and the places — online and in the post — where your letter can land.
THE SHORT VERSION
- A letter to a stranger works best when it is small, specific and kind.
- Decide whether you want a one-off gesture or a correspondence. Different places do each.
- Keep identifying details out, especially at first.
- You do not need to be a good writer. You need to be a real one.
Why write to a stranger at all
People who try it tend to describe the same three things. The first is relief: putting something into words for a reader who has no stake in it can be lighter than telling a friend. The second is perspective: the stranger lives somewhere else, maybe somewhere very different, and their reply reminds you how particular your own ordinary is. The third is simply the pleasure of giving someone a nice moment in their day, with nothing expected back.
A stranger is the only reader who meets you exactly as you are on the page.
What to say in a letter to a stranger
The blank page is the hard part. These are the kinds of things that work, because they are true and easy for someone else to picture:
- Where you are, right now. The chair, the light, the sound outside the window.
- A small thing from today. Something you ate, a conversation you overheard, the first cold morning.
- Something you are looking forward to, however tiny.
- A thing you have been thinking about lately and have not said out loud.
- A question you would genuinely like a stranger’s answer to. What does a normal Tuesday look like where you are? What is the best thing you ate this month?
- A small kindness. “Whoever you are, I hope this week is gentler than the last.”
Things to leave out, at least at first: anything that identifies you or where you live, and anything you would not be comfortable reading aloud to someone you had just met.
Five openings you can borrow
- “It is raining here, the soft kind that does not commit, and I thought I would write to someone I have never met.”
- “I do not know who you are, but I know you are reading this on some ordinary day, and I hope it is a good one.”
- “Today I learned something small that I cannot stop thinking about, and you are the first person I am telling.”
- “I am writing this at the kitchen table while the kettle boils. Let me tell you about the view.”
- “Can I ask you something I have always wanted to ask a stranger?”
If you are writing to someone who can reply, end with one real question. It is the difference between a letter that is read and a letter that is answered. For more ideas, see our 100 pen pal questions and letter prompts.

Where to send letters to strangers
One-off, anonymous exchanges
Letters from Strangers describes a daily, anonymous exchange: you write one letter, it is matched with another writer’s letter, and you receive theirs. Its FAQ says everyone can react with kindness, and that written replies and ongoing conversations are for premium supporters. DailyPenPal gives everyone the same question each day; you answer it as a postcard, and the next day a postcard from a stranger comes back. Both are beautiful for a small daily ritual with no ongoing commitment.
Strangers who can become pen pals
If you would like the stranger to write back — and possibly keep writing for years — a slow-letter app is the better home. On Snailpost, you are introduced to writers around the world by shared interests and languages, and your letter travels at the speed of real distance, so a reply from across the world takes a day or two to arrive. Letters can be translated on arrival, so the stranger does not need to share your language. There is also a Notice Board where you can pin an open letter for the wider community to find, which is about as close to a letter in a bottle as an app gets. Slowly, Letterbird and Penna work in a similar spirit; our guide to slow-letter apps compares them and the Snailpost vs Slowly page goes head to head.
Real paper, real post
Postcrossing gives you the address of a random member somewhere in the world; you send them a postcard, and once it arrives and is registered, another member sends one to you. You pay your own postage. It is the most tangible way to write to a stranger, and the card on someone’s fridge lasts longer than any screen.
Writing to strangers with care
A few habits keep letters to strangers kind for everyone, including you:
- Assume your reader might be having a hard day. Warmth costs nothing.
- Do not overshare in letter one. Some things are better saved until you know who is listening.
- Keep identifying details out: full name, address, phone, school, workplace, social handles.
- Never send money or move to another platform because a stranger asked.
- Use block and report without hesitation if something feels wrong.
On Snailpost, blocking and reporting are two taps from any letter or profile, and the app is for people 16 and over. The FAQ covers safety and privacy in more detail.
If you would like to try tonight, download Snailpost for iPhone or Android, write one honest page, and let the distance carry it.
Questions
Where can I write letters to strangers?+
Online, anonymous exchanges like Letters from Strangers and DailyPenPal send your words to someone you will probably never meet. Slow-letter apps like Snailpost and Slowly introduce you to a stranger who can write back, so a single letter can become a correspondence. Postcrossing sends a real postcard to a random address somewhere in the world.
What should I write in a letter to a stranger?+
Something small and true: what your day looked like, a thing you noticed, something you are looking forward to, a question you would genuinely like a stranger’s answer to. Kindness and specificity matter more than eloquence.
Is it safe to write to strangers online?+
Yes, if you keep identifying details out of the letter — no full name, address, phone number, school, workplace or social handles — and use a service with moderation and reporting. Never send money to anyone you meet through letters.
Can a letter to a stranger turn into a friendship?+
On services built for two-way correspondence, often. On one-off anonymous exchanges it usually stays a single kind gesture, which is lovely too. Choose based on which one you want.
The person who reads your letter will not know your name. They will know you were kind, and that is plenty.
