See why today's military is using Sandboxx for secure and private unit communications
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 convert each letter into physical mail. Mail call has never been so frictionless.
The best thing about Sandboxx letters - we include a postage paid and pre-addressed return envelope.
Send your letter before 5pm EST (M-F) and your letter will be created that night
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
Planning a trip to military graduation can be stressful but doesn't need to be. Our Military Travel Experts take care of everything with worry free cancellation.
