Turn your photos
into stamps.
Write real letters.
Stamp Letter is a pen-pal app where every photo you take becomes a collectible postage stamp on handcrafted stationery.
From camera to mailbox
Four quiet steps.

Frame something you love. A sunset, your cat, a doodle on a napkin.
It becomes a stamp
Your photo is printed onto a real postage stamp — perforated edges and all.
Write your letter

Someone opens it
They unseal the envelope, unfold the letter, and find your stamp inside.

Stamp Atlas
See where you've stamped.
Every stamp is geotagged. Your Stamp Atlas is a living map of everywhere you've been — cities, countries, continents.
Watch your journey grow month by month. See stats, unlock milestones, and discover how far your stamps have traveled.
The more you stamp, the richer your atlas becomes.
