Simplify your social unit comms in one place
The military journey starts at the recruiting station. Find every unit you have ever served with and stay connected.
Whether it's a simple "I love you", a memorable childhood milestone, or the pup missing his freedom fighter - snap a photo from your phone and write a message just as easily as a text.
Create a Sandboxx account with just a few taps.
If your loved one has already created an account, connect with them in the app. Not connected? You can still send them letters as long as you know their address.
We automatically and privately covert each letter into physical mail. Mail call has never been so frictionless.
The best thing about Sandboxx letters - we include a pre-stamped and addressed envelope with each parcel for swift return to you. We even include paper to write on.
Send your letter before 6pm EST (M-F) and, your letter will be created that night so it's on the way
Buy one for $3 or buy a bundle to save. We offer three different packages to choose from
A percentage of your letters will go to our partner non-profit organizations
Easy, Intuitive & Clean
Secure - Private - Simple
The greatest app that I have ever found. If you have a smartphone I recommend it for sending letters to your military family. They know how to take care of you!Melissa Carter Marine Mom
I like Sandboxx because it is a platform for service men and service women to keep in touch with each other and their kin to exchange ideas and share opinions.Jamail Bogany Army Specialist
I really like the new Sandboxx app. Thank you Team Sandboxx for helping us communicate with our loved ones when they're off the grid and away from home.Jeremiah L Dilley Family/Friend
