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.

Can I send a letter to someone else?

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.

How far into the future can I schedule a letter?

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

Is my letter private? Can others see it?

When writing a letter, you can choose one of three visibility settings: "Public Now" (visible after sealing), "Public on Delivery" (default, visible after delivery), or "Private" (only you and the recipient). We use encrypted transmission and secure storage to protect your content.

Will my letter be delivered on time?

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, generate a "claim code" as a safety net — no matter what changes, the code always works.

Can I edit a letter after sealing it?

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.

Do I need an account to write a letter?

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.

How do I reach you if I have a question?

Email us at help@postome.com and we'll get back to you as soon as possible.

Write a Letter to the Future

写给未来的你

Delivered

哈喽可爱的咩咩，今天收到了我的来信会不会有点意外呢。其实我也不知道今天为什么突然想给你写这封信。可能是因为今天看了电影有点感触吧，还记得2016.12.10我告诉你我去看电影了吗。看完这点电影我突然也也点脑抽了，就给你写了封信。

三个月后的罗美仁你好呀，我是三个月前的你自己，我想你一定记得，这是三个前历史老师布置的作业，也是我想对三个月后的自己的期待。你有没有好好听各个科的课呢？有不有按时完成作业呢？我想你会的，因为你想未来成为优秀的人，能被别人看着觉得是个成大器的
