What is a Sandboxx Letter?

A Sandboxx Letter is an electronically composed message that is printed into a physical letter, and sent to recruits in training. Sandboxx Letters are delivered overnight to base, making them faster than traditional snail mail.

We know that you have options when it comes to getting your message into the hands of your future service member. What is it about Sandboxx Letters that make them the best way to reach your recruit?

Every Sandboxx Letter includes:

  1. A shipping envelope that’s delivered to your recruit and carries all of the contents above.

  2. A pre-addressed return envelope to make replying back to you easier for your recruit.

  3. Your Sandboxx Letter copy, which includes up to 6,000 characters.

  4. An optional photo for you to include in your Letter.

  5. An optional military Exchange gift card add-on.

  6. Return stationery to make it simple for your recruit to write back to you.

Sandboxx Letters are:

  1. EASY.

    With Sandboxx, you can send a Letter directly from our app from the palm of your hand, wherever you are. We’ll then print it and deliver it.


    Each Sandboxx Letter includes a custom message that you write, a color photo for a more personal touch, stationary for your recruit to write back to you, and a pre-addressed return envelope.

  3. FAST.

    We use FedEx to overnight ship Letters to many basic training bases. Sandboxx
    Letters submitted by 4:30pm EST Monday through Friday arrive on base the next business day.


    We pre-sort all Letters that we send to base so that it gets through the mailroom, and into your recruit’s hands, faster.
