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 at most 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, every letter comes with its own "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.

《十年后的今天亲爱的你还是我的吗？》

“现在的你应该很幸福吧，挺好的。其实最近有在了解网络上发的校园霸凌的事件，有时候真的觉得霸凌者的好可恨呀，真的！然后我初中也被霸凌过，但是我不算特别过分，我就像是大事化小小事化了吧。。所以刚才又被看到你被骚扰真的很厌恶他们。要学会变坚强，大胆说不，，，也要走出自己的房间，去看阳光，去交益友！！！可能我的留言你不会看到，但是我的留言像是在三年后给你的一些安慰吧，亦或者像是太阳带给你的一丝丝温暖吧！加油”
