You know who it's for.
“I never told my dad what he meant to me. Now I can't.”
“I wrote my daughter a letter for her wedding day. She's only three.”
“There's an apology I owe someone. I'm not brave enough to say it out loud.”
“I want them to know how I felt. Even after I'm gone.”
You've typed it a hundred times. In Notes. In drafts. Then deleted it.
Letterbox gives those words a place to live — and a person to find them.
How it works
Three steps. That's all.
Write your heart out.
Take your time. Add photos. There's no send button — just you and your words. It saves as you go.
Seal it with a secret.
"What did we name the cat?" "Where did we first meet?" A question only they would know. That's their key.
Let it find them.
Share the link when you're ready. Or don't — we can send a gentle nudge. "Someone left you a letter."
Someone left you a letter.
If you got a link or an email that says “someone left you a letter” — it means someone sat down and wrote something just for you. Open it. Answer the question. Read their words.
Open Your LetterFor the words that matter most
Some things can't be said in a text.
"Open when you miss me."
Sealed envelopes with labels. They choose when to open — when they're sad, when they need courage, when they graduate, when they're homesick.
"Read this after I'm gone."
Write now. Designate trusted contacts. If something happens to you, your letters arrive. The words you wanted to leave behind — delivered.
"I need to say this, but I can't say it's me."
Write anonymously. Set a timer to reveal your name — or keep it hidden forever. Some words are easier without a face.
"If I don't check in, send my letters."
A quiet promise. Check in weekly or monthly. If we stop hearing from you, your trusted contacts are notified. Your letters find their way.
Letters people wish they'd written sooner.
To Mom
"Thank you for everything you gave up so I could have more. I see it now."
To my future kid
"I'm writing this the night before you're born. I don't know you yet, but I already love you."
To an old friend
"I'm sorry I disappeared. It wasn't you. I hope you know that."
To someone who'll never read this
"I think about you more than I should. I hope you're okay."
One-time. Forever.
