About this app

Are you tired of fleeting relationships?
Instead of quick swipes judged by looks or qualifications, try starting a warm conversation with a heartfelt letter.
Ddalklak Mailbox is an anonymous, analog-inspired random chat service that builds slow but deep connections.

[How to Use Mailbox]
Write a heartfelt letter, thinking of someone, and drop it in the mailbox.
The system will find a partner who meets your criteria (age, location, etc.) and deliver it.
Read the letter and if you're moved, accept it. A private 1:1 chatroom will open at that moment.

[What's Special About Ddalklak Mailbox]
📮 Exciting Waiting, Analog Matching
You don't have to stare at a screen and wait for someone to connect in real time. Just send a letter, go about your day, and before you know it, someone you're compatible with will reach you. Even the waiting becomes a pleasant thrill. Depending on your mood, you can set the mood of your letter: "Little Things in Life," "A Rainy Night," "A Sailboat on the Sea," "I Need Comfort," etc.

💬 Anonymous, Honest Conversations
Instead of profile pictures or complex personal information, only your nickname, age, and location are revealed. Get to know each other through your words and sincerity, without prejudice, and only engage in private chats with those who accept your letter.

📢 A Billboard for Sharing Little Things in Life
On days when writing a letter feels a little awkward, try leaving a short message on the billboard. A fleeting thought or a casual greeting might resonate with someone and spark a heartfelt reply.

🛡️ A Clean Environment for Peace of Mind
You can reject and block any abusive users or unwanted contacts at any time. Our rigorous 24-hour reporting system maintains a healthy and warm conversation environment.

🎁 Small Joys Every Day
Stop by the mailbox every day to check in and receive rewards.
