A letter to your child, written now, for when they’re grown.

For when they’re eighteen, written while they’re small. Seal it until the date you choose and keep the link somewhere safe. Letters and photos are kept for good, and a film is kept for a year after it’s first opened — so the one you record now is still there when they’re grown.

Letter to a child envelope: what goes inside

A letter

Who they are now, what they’re like at this age, what you hope for them. The things you’d want them to know.

Dear Finn, You’re three. You call spaghetti ‘pasgetti’. Please never stop.

A postcard

A photo of them now, and one of you now. They’ll want both.

You and me, the first summer.

A film

You, talking to them at eighteen, across all those years.

Stuck for words? How to write a letter to your future self

How it works

Fill the envelope with a letter, postcards and a film — any mix, up to ten pieces, and one price for the whole envelope by what's inside. Pay once, by card. Send the link now, or keep it sealed until the day: no app to install, it opens on any phone, and it's kept for good.

Letter to a child envelope questions

Where should I keep the link?

Somewhere you’ll find it in eighteen years: in your envelopes when you sign in, in the receipt email, and written down with the important papers.

Will the film still be there?

The link and the letter are kept for good, and a film is kept for a year after it’s first opened, so it’s there on the day and they can save their own copy.

How much does it cost?

$1.29 for letters and postcards, $5 with a film. One price for the whole envelope, up to ten pieces, paid once by card through Stripe. No subscription.

Do they need an app?

No. One link, opened in the browser on any phone, tablet or computer. They tap the seal and the envelope opens.

When should I send it?

Whenever you like. Send the link straight away, or send it now and set the day and time it opens — until then they’ll see the sealed envelope and a countdown.

Can I change it after I’ve paid?

Until they open it, yes. Sign in with the email you paid with and change what’s inside; the link stays the same. You can’t add anything that costs more than you paid, and once they’ve opened it, it stays as it is.

How long does it last?

For good. They can open it as many times as they like. A film is kept for a year after it’s first opened, and they can save their own copy.
