Heartstring has closed.

Monthly letter-writing kits that kept two people close — pre-stamped, pre-addressed, a fresh spark each month. We've had to wind it down. To everyone who wrote and waited by the mailbox: thank you.

“My daughter and mom were so impressed by these cards! They immediately filled them out and couldn't wait to read what each other had said.”

— Latoya

What it looked like

Each month, both people got a spark card and a pre-stamped, pre-addressed envelope to each other. Just write, seal, and drop it in any mailbox.

Heartstring spark cards and envelopes spread out — Kits for both people, every month.

Child writing a letter with crayons — A fresh spark — never repeated.

Mailbox with letters arriving — Pre-stamped, pre-addressed to each other.

Grandmother and granddaughter reading a Heartstring letter — A monthly moment with someone you love.

With gratitude,
the Heartstring team
