hi anonymous,
Welcome to The Unsent Letter Mailbox: NYC’s anonymous letter exchange.
You found us. Or maybe we found you. Either way, you’re here now—so kick off your shoes, take a breath, and let’s talk. 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 meant to be shared but not sent.
Why participate?
Because in a world of curated feeds and fast replies, sometimes the deepest things remain unwritten.
Stay a while. Read a letter. Submit one below.

Featured Letter of the Month
Exploring that strange in between zone where a friendship unexpectedly becomes more — where there is fear, and joy and a dash of mourning. To find ways to sustain friendship, even when there is unreciprocated desires might be the truest form of love, one that is forgiving and meets us where we are: unconditionally.
Writing Prompt: Dear friend, I want you to know this….
Not everything gets sent. Some things live in the scrapbox.
The letters that stay unsent don’t disappear—they live on in the Scrapbox, our newsletter of unfiltered thoughts, messy drafts, and handwritten confessions. Subscribe to the Scrapbox to read anonymous letters, get exclusive writing prompts, and be part of our growing community.
