About PostoMe

PostoMe has been a place for writing letters to the future since 2013. Write down what's on your mind, pick a date somewhere down the road, and seal it. We'll hold onto that letter and deliver it — to you or to someone you choose — the moment that day arrives.

How a letter survives years and still arrives on time

Delivery you don't have to chase

When delivery day arrives, we email and text the recipient automatically. Everything runs on Alibaba Cloud, with letters backed up multiple times over.

A claim code as backup

Every letter gets a 6-digit claim code. Even if contact details change over the years, that code can retrieve the letter anytime — write it on paper and hand it to someone, and it works just like a real key.

You stay in control

You can update the recipient's contact info anytime before delivery, so the letter still finds them years down the line.

Who runs this

PostoMe has been run by a registered company since 2013, with an ICP filing on record — keeping people's letters safe is all we do.

Letters delivered within a year are completely free. Longer time spans cost a one-time fee based on how far out you go (from ¥3.90, up to ¥19.90) — no subscriptions, no hidden charges.
