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.

Featured Letter of the Month

In May, Mental Health Awareness month, we’re celebrating deep truth(s), inquiring into our relationship with our own minds and inviting complexity.

Writing Prompt: Dear mind, this is the conversation I wish we could have…

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.
