Children can send and receive real letters through a parent-guided, reviewed mail process. Every letter comes to our PO Box first, is checked before forwarding, and home addresses stay private.

How Kindness By Mail Works
Choose a plan
Choose the option that fits your family.
Write your letter
Your child writes their letter at home, and a parent or guardian reviews it before sending.
Mail it to our PO Box
Print and complete the submission slip, place it with your child’s letter, and mail everything to our PO Box.
We review and forward
Approved letters are placed in a new envelope and forwarded through Kindness By Mail.
Return letters are reviewed before being forwarded, too.
Built for kindness. Designed for safety.
Kindness By Mail is not open messaging. Every letter goes through a parent-guided, reviewed mail process.
Parent review comes first
A parent or guardian reviews each child’s letter before mailing it to our PO Box.
Reviewed by our team
We review each letter for privacy, kindness, and appropriate content before forwarding.
Home addresses stay private
Letters go through our PO Box, so home addresses are never shared between families.
Approved recipients only
Children write only to other participating children through Kindness By Mail.
Child-led letters only
Parents may help write or type what their child wants to say, but adults may not send their own letters to children.
Replies are reviewed too
Any reply sent back through our PO Box is reviewed before being forwarded to your child.
