Big ideas, real impact.

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.

We love collaborating with spaces, institutions, individuals, and brands. Fill out the form below & let’s start the conversation.

  • The Unsent Letter Mailbox is a grassroots storytelling platform turning anonymity on its head.

    We believe in the power of what goes unsaid to foster true connection and empathy, helping us realize we are much closer than we think.

    Through temporary public installations and live anonymous writing events, our work invites people from all walks of life to get something off their chest. In exchange, they earn the right to read an anonymous letter written previously by someone else.

    We refuse to be a one-way stream of consumption — we are challenging our audience to actively engage. To earn their “write” to read. Learn more

Why give?

  • Because the city is loud, and we are drowning in the noise. Because our inboxes are full but our hearts are empty. Because somewhere right now, someone is carrying a letter they will never send — a confession, a confrontation, a love they never got to live.

  • The Unsent Letter Mailbox isn’t just a box on the street; it’s a rebellion against isolation. It’s a crack in the concrete where something real can grow. Every letter written is proof that we are here, that we feel, that we refuse to be erased by the endless scroll of algorithmic numbness.

  • Your support doesn’t just fund a mailbox. It fuels a quiet revolution in human connection. It puts ink on paper. It turns strangers into witnesses. It builds spaces where we can be unfiltered, unpolished, and—just for a moment—understood.

  • Give, because the world doesn’t need another notification. It needs more letters. It needs more raw truths.

  • The Unsent Letter Mailbox takes a city’s secrets and turns them into something raw, something real. Every anonymous letter is a brushstroke in a larger story, a collective self-portrait of what it means to be human.

  • Your support helps us turn fleeting moments of honesty into art installations, live readings, and exhibitions that make people stop, feel, and remember they’re not alone. Give, because someone’s unspoken truth might be exactly what the world needs to hear.
