Ratings and reviews

To begin with I wasnt very pleased with the app because it lost a couple of my saved drafts that I had put a good bit of time into, intending to go back and finish later, but they have excellent customer service which and thats hard to find these days. However, I highly recommend saving your drafts in your notes so you don't lose your progress if you dont intend to wrote your whole message at once.

The Sandboxx app provides a contemporary way to communicate with our recruit. There's no need for find an envelope, buy stamps, or drive to a mailbox. Writing a letter and sending a picture is as easy as sending a text message. The app is programmed to confirm receipt of each letter and notifies us when the letter is delivered. Finally, Sandboxx includes weekly updates on what our recruit is experiencing, suggestions for writing prompts, and so much more.

I've purchased 5 letters. Yet they dont allow me to use them. So I donated to our squad. no one is able to use them. very frustrating. You dont get weekly updates on your SIT unless you buy a letter. ridiculous. Then it makes it sound like the stamp and envelopes included for our Soldier in training. Nope you have to pay another $2 to add it. Its honestly better to just use the Post Office. I dont recommend this app. The idea is great if it worked better.
