An Open When Letter
Open When You Get the Promotion
For the version of them who is about to outgrow this letter.
Promotions are private celebrations, usually announced by email, often celebrated alone or with one person. A letter that shows up on the same day — sealed weeks or months earlier — is the proof that someone bet on them before the title made it official.
Write yours when you watch them do the work. We mail it on the date you pick — the week the announcement is supposed to land, or any later milestone.
Timing
When to have it arrive
Promotion timing is usually more knowable than it looks. Review cycles, fiscal-year starts and announcement emails tend to follow the same calendar year to year, so ask (casually) when decisions usually come out, or just remember when they did last time. Aim for that week. Since delivery has to be at least a month out, this is a letter you write while the work is happening, not once the rumor starts.
If the timing is fuzzy, pick a date shortly after the likely announcement rather than before it. An early letter just sits there, labeled and sealed, which is a lot of pressure for one envelope. A slightly late one lands in the first week or two of the new title, when the congratulations have slowed down and the self-doubt is moving in. That may be the better moment anyway, because it's when they start wondering whether anyone meant it.
Suggested Prompts
What to put inside
Pick one or two. The letter does not need to cover everything. It just needs to be specific.
- — The specific work you have watched them do that earned this
- — The reminder that they belong at the next level
- — Three things about the new role you think they will find harder than they expect
- — Permission to celebrate, openly, even if no one else does
- — The plan to mark it in person
One way to start
You got it. I'm writing this months before anyone decided anything, while you're still staying late to rebuild a forecast spreadsheet nobody asked you to fix. So I want to be on the record: I knew. I watched you take the meeting nobody wanted, train the new hire who kept calling you by the wrong name, and somehow still remember to eat lunch twice a week. The title is new. The person doing the job isn't. Go celebrate like you mean it, and then call me with every detail.
Skip These
What to leave out
- — Guesses about salary or the size of the raise, which can sting if the number disappoints and feel strangely transactional in a letter about them.
- — Digs at the coworkers who didn't get it, because a promotion letter that keeps score reads petty even if they'd secretly laugh.
- — A detailed game plan for the new role, since the first weeks will bring plenty of instructions and this envelope should simply say well done.

Frequently Asked
The short version
What is an open-when letter?
A sealed letter labeled with the moment it should be opened — “Open when you miss me”, “Open when you can't sleep”. The tradition started in military families; the format is now used by everyone in any long-distance or high-stress relationship.
How does delivery work?
You write the letter (digital $9 or handwritten $19), pick a future date one month to two years out, and we mail it on the morning of that date. Real envelope, real wax seal, US mail.
What if they do not get the promotion?
Email support and we will hold the letter for the next attempt. Same letter, re-aimed at the next yes.
Should this be from a boss or from a partner?
Either works. Bosses are not allowed to bet on their reports in this way often, and partners do not always have language for professional wins — both are valid angles. The letter sounds different in each voice; trust yours.
Does this work for a new job instead of an internal promotion?
Yes. A new offer, a first management role, a tenure decision, making partner — any professional yes with a rough date attached works the same way. Aim for the start date or the first week, when the novelty is high and the doubts haven't settled in. If it's a new employer, send it to their home address rather than the office.
Is it strange to write this before I know they'll get it?
Not strange — that's the whole appeal. The letter is evidence you believed in them before the result came in. Write about the work you've seen rather than the outcome, so every line holds up either way. A page that lists specific things they did well is just as true on the day of a yes as it is today.
