What is Yuubin?
Yuubin is a digital letter-writing platform where messages take exactly 24 hours to be delivered. It brings back the charm of traditional mail with a minimal, cozy interface. No notifications, no read receipts, no pressure for immediate responses.
Problem
Users miss the immediate, lack anticipation and impersonal nature of traditional digital communication (email, instant messaging), craving deeper connections through slower, intentional exchanges.
Solution
A digital letter-writing platform with 24-hour delivery and a minimal, no-notification interface, allowing users to write and receive letters with enforced delayed delivery (e.g., 24h wait time per message).
Customers
Writers, creatives, remote workers, and digital minimalists aged 20-40 who value mindfulness, nostalgia, and reducing digital burnout through slower communication.
Unique Features
Enforces 24h delivery delay for all messages, removes read receipts/typing indicators, and mimics physical mail’s tactile UI (e.g., envelope-opening animations, static letter storage).
