Each one opens a blank letter with the moment already on the envelope. No account needed.
Friday is coming. I know this week took everything you had, and the coffee machine broke too, which feels personal.
Close the laptop. Take your shoes off. Order the good noodles and put it on my tab. You are allowed to be done.
Next week can start on Monday like everyone else's.
An open when letter is a letter written for a moment instead of a date. The writer picks the moment: a bad day, a first day, a night when sleep will not come. Then the writer seals the letter, and the reader keeps it until that moment arrives.
The classic version is paper. Someone writes a handful of letters, puts each in its own envelope and labels the front: Open when you miss me. They hand the stack over as a gift, often to a partner who is moving away, a friend starting college or a child leaving home.
The label is the whole trick. A birthday card arrives when the calendar says so. An open when letter arrives when the person needs it, and the reader decides when that is.
We wrote these to show what a letter like this can sound like. Borrow a line, then make it yours: the small, true details are what make it land.
You have the keys. Stand in the empty living room and turn in a circle. Be loud. Nobody can hear you yet.
I was twenty-six when I got mine, and I sat on the floor with a sandwich for an hour. Best lunch I ever had.
Welcome to your own place. I'm bringing a plant that is very hard to kill.
You are not doing it wrong. Babies cry, and some nights there is no reason you can find.
Hand the baby to someone if you can, and take five minutes with the door closed. A cup of tea, a glass of cold water, whatever you can manage. It passes. It really does pass.
I'm one text away, and I'm awake.
Put the pen down. You're done. Whatever the paper said, it's over, and no amount of replaying question six will change it.
Go outside. Eat something that isn't a granola bar. Sleep until noon and then do nothing on purpose.
You worked harder this term than you think you did. I watched.
Right now, as I write this, you're in your second week at the new job and the apartment is still half boxes. You told me you were scared you'd made a mistake.
I don't know what day you're opening this. If it's a hard one, remember the boxes. You walked into all of that and kept going.
I'm writing so you can see how far it goes from here.
The same idea goes by a few names: open it when, open me when letters, open this when letters, or just open when. The wording on the envelope changes from person to person, but the idea does not. A moment on the outside, a letter on the inside, and a reader who chooses when to open it.
Most people use "open when" for the whole set, and each envelope gets its own line, such as "Open when you graduate" or "Open when you can't stop worrying." For a long list of moments to borrow, see the open when ideas.
On Open When you write the letter, choose the moment and seal it. Writing and reading are free, and nobody needs an account. You can leave an email if you like, but it is optional.
You pick a wax seal color and a handwriting style, and you can add one song as a link the reader opens with the words. Then you choose how it travels. The reader can get an email saying a sealed letter is waiting. The email never contains the words. Or you can give them a private link or QR code yourself, or keep the letter for now.
The reader decides when to open it. Every letter also has a date that you choose, and it cannot be opened before then. Until it is opened, you can unseal and edit it. You can delete it any time, before or after, and download your own copy. Once it is read, the reader can send one tap back: "It helped," "I needed this," "Made me laugh" or "Thank you."
The honest answer is when the moment on the label is true. An envelope that says "Open when you miss me" should wait until you do. If you open it early out of curiosity, you will have used it up.
On Open When, each letter also stays locked until the day the writer picked, so it cannot be opened too soon.
Pick one person and one moment you can picture them in. Write for five minutes without stopping, then cut it down. If you want to see finished letters first, the examples page has ten. If you would rather make paper envelopes by hand, the printable guide covers cards, envelopes and an open when book.
Open When never writes your letter for you. These are only here to get the first line down.
