About this app

It’s okay if you don’t know their contact information. As long as you remember their name, birthday, and the school they attended, you can send them a letter that feels like a handwritten note.

■ How to Receive It

· Write a letter based on the recipient’s known information, such as their name, birthday, or school (graduation year).

· The more criteria you have, the more likely the recipient is to receive it.

· The person whose criteria match theirs goes through identity verification and opens the letter from their inbox.

■ In the Inbox That Person Will Open Someday

· It’s okay if that person isn’t using this app right now.

· The letter you sent remains addressed to them and will be found in their inbox on the day they check it out.

· Keep an eye on your inbox while you wait — you will be notified as soon as it arrives.

■ With Peace of Mind

· Identity verification is required to receive the letter. This ensures that only the recipient can open the letter sent to that specific criterion.

· You can report or block inappropriate letters at any time.

· You are limited to sending only one letter per day. So, be extra careful and sincere. ■ Convey these feelings

· To a classmate from your school days, greetings you never managed to send

· To a first love you parted ways with long ago

· To someone you couldn't tell thank you or apology to

Now, try putting a letter in that person's mailbox.
