Hi Anonymous,
Welcome to The Unsent Letter Mailbox: NYC’s anonymous letter exchange.
The Unsent Letter Mailbox began in New York City in February 2024, offering a home for unsent letters, anonymous confessions, unspoken thoughts, and raw truths.
Here’s how it works: You write an anonymous letter, drop it in the mailbox, and in exchange, you get to read one written by someone else. Hundreds of New Yorkers have participated—leaving behind love letters, regrets, unsent goodbyes, secret confessions, and fragments of stories never meant to be sent.
Why participate?
Because in a world of curated feeds and fast replies, sometimes the deepest experiences remain unspoken.
Stay a while. Read a letter. Submit one below.

Let’s turn anonymity
on its head
Support the mission. Fund the unheard. Because silence doesn’t change the world—words do.
