Share Sandboxx with others to get free letters.
How do I earn free letters?
01. Share your link
Invite your friends and family to join Sandboxx with your unique link.
On the Letters screen, you’ll see an option to earn free Letters. You’ll be able to earn these credits by sharing Sandboxx with your friends and family. Tap “Earn Free Letters” to get started.
Next, use the “Send invite” button to share Sandboxx with your friends and family, either via SMS, email, or through another app of your choice (like Facebook Messenger, or WhatsApp).
02. Sign Up & Send
Once someone signs up for the first time through your link, they’ll need to purchase a credit for their first Letter and send it.
03. You both get free letters.
Once your referral sends a letter, you both earn a letter credit ($4.99 value). Referral Rewards are non-transferable, are not redeemable for cash, and are subject to change without notice.
To see a complete overview of all of your referrals and the credits that you’ve earned, you can tap “Your earned Letter credits” to access all of this information.
