Dear anonymous,
Welcome to The Unsent Letter Mailbox, a movement providing creative engagement through free pop-ups, ticketed events, collaborations with artists, and partnerships with brands.
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. Thousands of New Yorkers and writers from around the world have participated—leaving behind love letters, regrets, unsent goodbyes, secret confessions, and fragments of stories never meant to be sent.
Why participate? Because you deserve to get it off your chest, because someone else deserves to feel less alone, when they find your letter. Because we believe human connection is dope.
The best way to participate is IRL. Check out our events.
Stay a while. Read a letter. Submit one below.
Dead Letter Dial

This is a dead letter dial - An ode to the now defunct (pun intended) dead letter office (DLO) established by USPS in 1825. The DLO was where unclaimed, undeliverable and illegible mail would go to find eternal rest. Unclaimed items were eventually auctioned off to the highest bidder - which, much like we did by setting up the phone at the Inexpressible Contained exhibit in Chattanooga, Tennessee, suggests that what may be unclaimed, is not for that reason - void of value.

Let’s turn anonymity
on its head
Unsent Letter Mailbox is a fiscally-sponsored multi-disciplinary group, that provides creative engagement through free pop-ups, ticketed events, collaborations with visual and performance artists, and partnerships with institutions and companies.
Our fiscal sponsor is Nuyorican Poets Cafe, operating as a tax-exempt non-profit. We rely on generous individual donations to fully fund our urban pop-up programing, support our free submission platform, and expand programming to other cities in the USA.
Your tax-deductible contribution helps us continue our mission enabling individual catharsis through the art of anonymous letter writing, and bridge between cultural and political divides.
