Six different “open when” cards laid out on a table.

“Open When…” Letter Topics


In the world of modern communication, we are used to instant responses from those who are important to us. But there are times during a service member’s training or deployments when they are unable to communicate as quickly as we would like. Sometimes they have limited access to their phones, or no internet access, or they have to wait in line to send an email. Even with ideal technology connections, the time zone difference may put a damper on live conversations. During these times of limited communication, how can we ensure that our loved ones in the military can hear from us when they need it most? We need “open when” letters.

An “open when” letter is a note written ahead of time to address a specific emotion or event, then sealed in an envelope to be opened at the appropriate time. It’s common to prepare letters such as “open when it’s your birthday” or “open at midnight on New Year’s” so that couples who are separated by great distances can still feel connected during these special moments. You can fill the envelopes with a simple message, or even a few small gifts. Many military spouses or significant others prepare a large stack of these letters before a deployment, and then tuck them into the service member’s bags to find after they depart. It’s easier to say goodbye knowing that you are sending your love and affection with them on the journey.

The beauty of an “open when” letter is that it offers exactly the emotion needed in a particular moment. The message might make the reader laugh, cry or smile, but it is a loving message that reminds them how much someone else is missing them or cheering for them in that moment. It’s timely, thoughtful and a great way to build up your relationship over the distance!
