An Open When Letter
Open When You're Deployed
For the year that does not pass like a year.
Deployment is the original use case for open-when letters — the format was born in military families. The reason it works is that deployment time moves differently. The letter you wrote in March, opened in October, feels like a postcard from a previous lifetime.
Write yours from inside the house they are leaving. Describe the rooms, the dog, the weather, the chores you are not going to finish. We mail it on the date you pick during their deployment. Anywhere from one month to two years out.
Timing
When to have it arrive
The most useful date for this letter is usually one when your service member is back at a home address. Homecoming week is the natural choice: a letter written the week they left, waiting at the house they come back to. Return dates move, so lean a few days later than the date on the paperwork rather than earlier — a letter that arrives after they're home gets opened by them, not set aside by someone else.
The other route runs through family stateside. Send it to the spouse, parent or grandparent at home, and let them keep it sealed for the day it's meant for — the first phone call home, the halfway point, the drive back from the airport. You can set it anywhere from one month to two years out. A typical deployment fits inside that window, which means you can write the letter before they leave and still have it waiting at the end.
Suggested Prompts
What to put inside
Pick one or two. The letter does not need to cover everything. It just needs to be specific.
- — What the house sounds like at 7 PM
- — What the kids said today that they would have laughed at
- — Three things waiting for them to come home and do
- — What you are eating, watching, reading without them
- — Permission to feel the weight without minimizing it
One way to start
You left on a Tuesday, and by Wednesday the house had started keeping its own count. Your boots are still by the back door because neither of us could bring ourselves to move them, and Biscuit checks on them every morning like they might have news. I'm writing this the first week, while the quiet is still loud, so you'll know exactly how it was here at the start: we were okay, we missed you, and nobody sat on your side of the couch.
Skip These
What to leave out
- — Money problems, car trouble, or the leak under the sink you're already handling, since they can't fix any of it from where they are and will worry anyway.
- — Details about their unit, location or movements, even the ones you've heard secondhand; keep the letter about home, not about the mission.
- — A countdown to a specific return date, because those dates move, and a letter that promises a day that doesn't happen lands harder than one that never named it.

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.
Can we send this to an APO/FPO address?
No. We only mail to standard US home addresses, not APO/FPO or overseas military mail, which adds weeks and a lot more chances for a letter to go astray. Send it to the house they're coming home to, or to a family member stateside who can hand it over in person.
Should I send multiple letters across the deployment?
You can write a small set: open when you miss home, open when finals (for spouse), open when you cannot sleep, open when the deployment is halfway done. Each is a separate order.
Can I write it before they leave?
Yes, and there's a good case for it. The weeks before a deployment are full of things nobody says because everyone is busy being practical. Put them in the letter, set the delivery date for the homecoming window or a family member's address, and order. Any date from one month to two years after you order works.
Can the service member write one for the family at home?
Yes, and it might be the better direction. Before shipping out, they write to a spouse or kid and set it for a hard stretch they'll miss: a birthday, the first day of school, the halfway point. It arrives at home in their voice while they're gone. Handwritten ($19) means their actual handwriting shows up.
