Make a promise to someone you love — in writing, in your own hand, with a date attached. We deliver the letter on the date you set.
We make a lot of promises and document very few of them. The vows we make at a wedding mostly live in the videographer's footage that nobody watches again. The promises we make to our kids about what kind of parent we'll be, the promises we make to ourselves about who we'll become — almost none of them get written down. They live as intentions, and intentions decay.
A promise letter is a different kind of commitment. You write today, by hand or digitally, the specific promise you're making and to whom. The version of you who's making it. What it would look like if you keep it. What it would look like if you don't. Then we deliver the letter on a date you choose — an anniversary, a birthday, the date the promise was supposed to be fulfilled by — either to the person you made it to, or back to yourself for accountability.
The form is most powerful for promises that are easy to break and hard to keep: a promise to your partner about how you'll show up for them in this next year, a promise to a child about something you want them to know you committed to, a promise to yourself about how you'll handle a recurring failure mode. The letter doesn't make breaking the promise impossible. It just makes it harder to forget you made one.

Your letter is in safe hands
You're trusting us with something irreplaceable. Here's what we do about that.
Letters are stored in climate-controlled, fireproof safes — not filing cabinets or cardboard boxes. We treat every letter as irreplaceable, because to someone, it is.
Every letter ships with an active tracking number, so you (or the recipient) know exactly when it's on its way.
If your address changes before your delivery date, email us anytime and we'll update your file. Your letter follows you — no extra fee.
If Hold My Letter ever closes, every stored letter is immediately mailed back to the sender's return address. No exceptions.
One letter. One delivery. One beautiful moment when it returns.
