Paper remembers what
time forgets.
Mailbox Kid helps children send real letters — to grandparents, friends, and the people they love. Every month. No effort. Just connection, on paper, in their own handwriting.
They grow up.
The letters stay.
A photo lives on a phone. A video gets buried in a folder. But a letter — with their handwriting, their spelling mistakes, their little drawings in the margin — that's something else. That's a piece of them, exactly as they were.
Something to hold
When they're grown and gone, you'll reach for the letters. Not the apps. Not the photos. The letters.
Proof it happened
Words on paper are evidence of a moment that once existed. A childhood, in their own words.
A piece of them
Their handwriting is theirs alone. It changes. It grows. Catching it now is catching them now.
"I keep meaning to have them write to grandma."
You want your child to be the kind of kid who sends real letters. You've thought about it. You've even started to set it up. But then life happens — and it doesn't.
It's not that you don't care. It's that there are too many little things standing between intention and action.
We removed every single
reason it doesn't happen.
Every month, a kit arrives with your child's name on it. Everything is inside — paper, prompts, envelope, stamp. Even a little guidance for you.
Your child opens it. Chooses who to write to. And sends a real letter. No planning. No prep. No pressure. It just happens.
Simple enough for a 4-year-old.
Meaningful enough to keep forever.
Your job is to subscribe. Their job is everything else.
They get mail with their name on it
Every month a kit arrives addressed to your child. Not to you. To them. That detail matters more than you'd think — it's already theirs before they open it.
They choose who to write to and write
Prompts guide them so there's no blank page panic. They choose who deserves a letter this month — grandma, a cousin, a friend. Then they write. In their own words, in their own handwriting.
They seal it, stamp it, send it
The stamp goes on — one of their favorite parts. Into the mailbox it goes. Done. No parent prep, no trip to the post office. Just a real letter on its way to someone who will keep it forever.
Everything they need is already inside
A directions card walks them through mailing a letter step by step — written for kids, not parents. They don't need you hovering. That's the whole point.

Choose the level that fits where your child is right now — not their age.
Starter
Maximum guidance. Every section filled with prompts so even a child who can only write a few words can send a meaningful letter.
Growing
A balance of structure and freedom. Enough guidance to feel supported, enough space to find their own voice and style.
Independent
Minimal guidance. A theme, a mission, and the space to write a genuine letter completely in their own words.

"This is so awesome. I'm going to write him back!"
— Brandon, age 14
Brandon received a letter from his 5-year-old cousin. He hadn't asked for it. He didn't expect it. But he read it three times — and immediately wanted to write back.
That's the whole point.
The secret is what happens after the letter.
Most activities work once. Mailbox Kid builds a real habit because it creates something most activities don't: a reason to do it again next month.
When grandma gets a letter — and writes back — your child becomes a real correspondent. Not because you told them to. Because they wanted to.
More than one kid?
Add a subscription for each child at checkout. Every kit is personalized with their name and matched to their level. Each child gets their own mail — which matters more than you'd think.
Some things are worth holding onto.
"I have every letter my granddaughter ever sent me. I read them when I miss her. Her handwriting when she was six is my favorite thing in this world."
Start with a letter. Build something that lasts longer than childhood.
"I wanted my kids to have this kind of childhood. So I built the system that makes it happen."
Mailbox Kid started with a simple observation: every parent we talked to wanted their child to write letters. Almost none of them did it. Not because they didn't care — but because the gap between intention and action was just wide enough to stop them every time.
So we closed the gap. Mailbox Kid is a correspondence habit system — not a craft box, not a toy, not a busy activity kit. It's the thing that makes a meaningful thing actually happen.
Questions we get a lot.
What age is Mailbox Kid for?
Mailbox Kid is designed for children ages 4–17. We have three levels — Starter (ages 4–6), Growing (ages 7–9), and Independent (ages 10–17). Not sure which level? Start with Starter — you can switch anytime.
What's included in each kit?
Simple Mail — $12/mo: 1 letter sheet with guided prompts, 1 envelope, 1 real Forever stamp, a sticker sheet, and a monthly Mail Mission.
Mailbox Kid — $24/mo: Everything above times two — so your child can write to two people every month — plus a wax seal sticker.
What's the difference between a subscription and a gift?
A subscription renews automatically each month — cancel anytime. A gift is a fixed term (3, 6, or 12 months) with no auto-renewal. See gift options →
How is this different from pen pal subscription boxes?
Most pen pal boxes match your child with a stranger. Mailbox Kid is different — your child chooses who to write to. Grandma. A friend. A cousin. Someone they already love. A stranger might write back once. Grandma will keep every letter forever.
Do I need to provide stamps or addresses?
Nope. A real Forever stamp is included in every kit. Your child also addresses the envelope to whoever they're writing to. For younger writers, you may need to help the first time.
How much parent involvement is required?
Very little — that's the whole point. For Starter level (ages 4–6), you may want to sit with them the first time. After that, most kids run with it.
Can I subscribe for more than one child?
Yes — each child gets their own kit with their name on it. Add multiple subscriptions at checkout and include each child's name and level in the order notes.
Can I cancel or pause my subscription?
Yes — cancel or pause anytime, no questions asked, through your account portal.
