Private email with teeth.

We are not accepting new users. The door is shut, Japan is already moving, and the waitlist is the only visible crack.

Mail Pressure

Built for inboxes that cannot afford to look soft.

Not for everyone

When we open the gate, slow users lose.

Send Wisp is being shaped as a harder private email layer: direct, clean, and hostile to inbox noise. You can stare at the login. You cannot force the door.

Send Wispは、静かで鋭いプライベートメール体験を目指しています。
