Frequently Asked Questions

PostoMe is a "future letter" platform. Write a letter, choose a delivery date — tomorrow or ten years from now — and we'll send it to the recipient via email or SMS when the time comes. It could be a promise to your future self, a surprise for a friend, or a message across time to someone you love.

Absolutely. Enter the recipient's email or phone number, and we'll notify them on delivery day. You can also skip the contact info and generate a "claim code" instead — hand it to them in person, just like a real letter.

Anywhere from one day to 30 years. Letters due within a year are completely free. Longer time spans cost at most about as much as a cup of coffee. We'll safeguard your letter until the day it's meant to be opened.

When writing a letter, you can choose one of three visibility settings: Public Now (the default, visible after sealing), Public on Delivery, or Private. The choice is shown clearly before sealing and you can switch to Private. We use encrypted transmission and secure storage to protect letter content.

Our delivery system checks for due letters every minute and dispatches them immediately. If you're worried about the recipient's email becoming invalid or phone number changing, every letter comes with its own "claim code" as a safety net — no matter what changes, the code always works.

Once sealed, the letter content is locked — that's by design, like mailing a real letter. But before delivery, you can still update the recipient's contact info or generate a claim code.

You can start writing without logging in — capture your inspiration the moment it strikes. Saving drafts, sealing letters, and viewing your history require an account. Signing up takes just seconds with your email or phone number.

Delivery under one completed calendar year is free. Each completed year then costs ¥1.99, capped at ¥19.90 from year 10 onward, paid once with no subscription. A "TimePass Card" covers one letter scheduled up to 30 years ahead.

This is the question we hear most often, and the one we take most seriously. Founded in 2012, PostoMe has operated continuously under a registered company, with letters backed up multiple times over. Even in the unlikely event the service ever changes hands, we're committed to notifying every user in advance and letting you export your letters.

Every letter gets an 8-character claim code the moment it's created. Write it down, tuck it into a physical envelope, and hand it to them yourself — on delivery day, they can claim the letter on the site with just that code, no account needed.

Public Now is selected by default, so a letter appears in the public archive after sealing. You can switch to Public on Delivery or Private before sealing. Private letters never enter the public archive and can only be read by a verified recipient.

On delivery day, the system automatically sends an email (if the recipient has one on file) and an SMS (if there's a phone number), plus an in-app notification. Every channel is tracked with delivery receipts, and the sender is notified if anything fails.

Yes. Log into the Mini Program with WeChat, link that same WeChat account on the website, and your letters and account data stay fully in sync. Returning users can also recover their original account from inside the Mini Program using their email or phone number.

Letters are a private space for personal expression, so we don't manually review them. Every letter goes through automated content moderation, and anything that breaks the rules (political content, explicit material, violence, and so on) can't be sealed.

No — that's by design. Once a letter is sealed, not even you can reopen the text before delivery day, just like dropping a real letter into a mailbox. That's what makes the moment you finally open it feel like a real surprise.

Right after the college entrance exam or grad school exams, at graduation, when a child is born, on a wedding anniversary, on New Year's Eve — really, any moment you want to say something to the future. Browse our themed letter collections to see what other people wrote at moments like these.

Check your spam folder first. If you're a registered user, delivered letters also show up under My Letters → Received once you log in. Lost the claim code? The sender can always look it up again from their letter management page and pass it along to you.
