A safe place for words that need time.

About Someday Post

Someday Post helps you send letters and small sealed keepsakes to a future date of your choosing—from 30 days to 20 years away. Write to your future self, your newborn at eighteen, your spouse on an anniversary, or gather a whole room of people around one shared milestone.

Our promise

Trust is the product. Letters stay sealed and unread. Future delivery costs are held in a funded reserve, and yearly address check-ins plus backup contacts help each delivery find its recipient even when life moves on.

Why we built it

The most meaningful things are often understood later. We give today’s words a safe place to wait until the day they matter most.
