Sandboxx Letters for Your Recruit in Boot Camp

Sandboxx is a paid electronic mail service to send letters to your recruit in boot camp in shorter time than standard US Mail.

In just four easy steps you can send a letter to your recruit in boot camp with the Sandboxx app. With Sandboxx, you can type a letter from your phone, add a photo and hit send. Sandboxx will securely print your message and deliver it to your recruit. All letters sent before 5pm EST are delivered to the base the next business day. Sandboxx pre-sorts mail by company and platoon so that when it gets to the base, your recruit will receive it faster. Sandboxx also includes a self-addressed return envelope so that it is easier for your loved one to reply.

It takes four steps for the first send, but thereafter, it's just a couple clicks. Here's how to get started:

You need your communication with your recruit to be safe, secure and private. Sandboxx provides safe, secure, and private mail.

From the Founder of

Dear Recruit Family Members,

Sandboxx is working directly with the United States Marine Corps at both Marine Corps Recruit Depot in San Diego and Parris Island. This will impact how and when you send mail to your recruit.

Effective April 10, 2017, our policy will be that you may begin writing to your recruit as soon as you receive his/her address. You may receive the address in one of three ways:

  1. From his/her Recruiter
  2. From the form letter your recruit will send you from MCRD, or
  3. From Sandboxx as a text message

When you get your recruit's platoon number and address from one of these three sources, you can start sending letters. It is always possible that a platoon number or address may change. Accept that as a possibility and start writing to your recruit.

The "Last Call" for letters to your recruit in boot camp through Sandboxx will be the same week as graduation; send your letter by 5:00 p.m. Eastern Time on Tuesday before graduation for delivery to the Depot on Wednesday prior to Family Day on Thursday and Graduation on Friday.

We're looking forward to a great partnership with Sandboxx!

God Bless and Semper Fi,
Tracy Della Vecchia
