Letters for the future
Write a letter or seal a small keepsake now. Choose any delivery date from 30 days to 20 years away, and we’ll make sure it finds its way back.
Our promise
Sending something years ahead asks for more than postage. We’re building Someday Post around clear safeguards from day one.
Sealed means sealed
Your letters remain private, unread, and protected until their chosen opening day.
Delivery funded
Future delivery costs are held in a funded reserve designed to support long-horizon promises.
Moves accounted for
Backup contacts and yearly address check-ins help your someday reach the right place.
Made for milestones
Write to next year’s you, your newborn on their eighteenth birthday, or the person you’ll still love on your tenth anniversary. Choose 30, 90, or 365 days for a near-term reveal—or save it for decades.
Add a photograph, tiny memento, or handwritten note to a capsule box made for the waiting.
Invite wedding guests, classmates, relatives, or friends to contribute letters to one shared future date.
