If you used Sandboxx to write letters during basic training, you already know how easy it is to stay connected. During basic training, Sandboxx provides overnight service and tracking directly to basic training locations so recruits get their messages fast, with full delivery visibility.
After graduation, your service member moves to a new training or duty location. This is not a location where Sandboxx provides overnight shipping with tracking. However, you can still use Sandboxx to stay in touch!
You can write letters through Sandboxx to any U.S. address after graduation. These letters are sent via standard USPS service, and typically arrive within 2–3 days.
Letters for Every Stage of Service
Sandboxx isn’t just for boot camp. You can continue sending letters throughout your military member’s career — even when they’re stationed or deployed overseas. Letters can be sent to APO/FPO/DPO addresses, allowing your words to reach them wherever they serve.
Please note: letters sent after basic training will always remain in “sent” status in your app. They will not move to a “delivered” status, so it’s best to confirm directly with your recipient once they’ve received it.
A New Chapter of Support
Graduation isn’t the end of the journey — it’s the start of a new one. As your recruit grows into a full-fledged service member, your letters remain a steady reminder of home, love, and pride.
Whether it’s a quick note or a heartfelt update, your words still matter. They’re proof that distance doesn’t end connection — it only changes how you send it.
