你好呀未来的我,现在是2020年十一月的最后一天,今天在抖音上看到这个时光邮局,想了想还是来写一封信给你,现在的你离梦想还远吗?有没有在为自己的梦想努力拼搏,父母身体都还好吗?奶奶已经去世一年半了。有没有谈男朋友呀?男朋友帅不帅?是不是和我

你们还在一起吗?我只是希望你们还在一起。虽然两个人两种性格,一种热情,一种冷漠,但是你们彼此许诺过。如果这个时候你们已经做了彼此的路人,请你要记得,当初不经意间许下的诺言你也一定要遵守。不要选择忘记,也不要选择记恨,因为你们做的决定都将会伤

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 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" (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.

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.

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.
