A collection of lost words, unsent letters, and bottled messages left for strangers to find. Some words are meant to stay unread.
Stamped Not Sent is a project for words that were never sent.
Tiny bottles with letters are hidden in different places. Online, people can also share anonymous notes.
It’s a way to give unspoken thoughts a home and maybe let them reach the right person at the right time.

Somewhere in the city, a small bottle is waiting.
Inside: a note and a question.
Clues are shared on Instagram @stampednotsent or via Mail:
[email protected]
If you find one, it’s yours, keep the note, or share it.
Each bottle is a secret treasure, waiting for the right person at the right time.


Anyone can share an anonymous letter.
Some will be published here and on Instagram,
so hidden words can be seen and felt.
You can also respond with your own story,
your own feelings, your own words.
Submit a Letter: Share an anonymous note: a thought, a memory, a confession. No names, no judgment.
Find a Bottle:
Follow the clues on @stampednotsent to discover real bottles hidden in the world.
Read & Reflect: Explore the archive of anonymous letters and let the words stay with you.
Because sometimes, just writing it down is enough.
