24 alternatives to Three Kind Words – Spread kindness one mysterious postcard at a time
Ever wish you could anonymously drip-feed kindness through the mail? I tried answering that with Three Kind Words (https://threekindwords.com), a vending machine that sends three mysterious postcards over three weeks, slowly revealing a message. Here’s how it works: you pick a three-word message (like "You are awesome" or "I love you"), and each word is printed on its own postcard, mailed one week apart to your unsuspecting recipient.

Hi everyone — I’m Clark, creator of Keeps, a way to send physical postcards that play your voice with a quick QR code scan.
