### 5/5 — Get it!

*2026-08-25, version 20.49.0*

This app is amazing! I’m so grateful to be able to use this to stay connected to my sailor. Letters get sent next day if you send between Monday-Thursday. You do have to pay but it’s worth it!!! You also get weekly updates so you know what your service member is going to be doing this week!

### 5/5 — Amazing app and service.

*2026-08-25, version 20.49.0*

This app and service are top notch. Knowing my letters are getting to the base helps. The costumer service is amazing.

### 5/5 — Sandboxx!

*2026-08-24, version 20.49.0*

LOVE THIS APP! Not only does it do a phenomenal job of keeping us connected to our military recruits, but! It excels at providing us with information and resources throughout their journey!

### 5/5 — Thankful for Sandboxx

*2026-08-23, version 20.48.1*

This makes writing to my SIT so easy and quick!  No worries about my letters not getting to him.  You have to pay for this but it is so worth it!!!!

### 5/5 — Thank you so much

*2026-08-23, version 20.48.1*

Modern technology can really feel like the only way to communicate sometimes. Thanks to sandboxx I could connect with someone I truly appreciate and care for.

### 5/5 — Easy, Fast & Reliable

*2026-08-23, version 20.48.1*

I love how quick, convenient and reliable Sandboxx is. I had an issue(which was my fault tbh) with my letters after I changed the address, but after reaching out for help, a real support agent was quick to respond, fix the issue, and get my letters sent out. I really appreciated how helpful and responsive they were!

### 1/5 — Make sure you check address

*2026-08-23, version 20.48.1*

One of the letters my daughter wrote was returned and updated the address in time for her friend to switch bases and be returned again. I sent a gift card and her friend never got the card, very frustrating when this is is supposed to be an easier system.

### 5/5 — Love the app

*2026-08-21, version 20.48.1*

I love this app it help me keep in touch with my sin while he was at bootcamp, very happy cuz we were able to send him letters  and they gave him an envelope to write us back.

### 2/5 — Change up after buying

*2026-08-21, version 20.48.1*

I don’t like nor appreciate the fact that when I bought the package, it was stated that my letters would come with a letter, a picture and a pre-addressed envelope for my recruit to write back and all the sudden that pre-addressed envelope to write back is no longer included with it.  Had I known that, I’d not have wasted my money. I shouldn’t have to pay extra for it when it was included in the package when I bought it.

### 5/5 — Sandboxx is great

*2026-08-21, version 20.48.1*

The sandboxx app has been the best thing for any military parent to communicate with your loved ones without the worry if they got your letter or if it got lost in snail mail.
