Skiff Mail

Skiff Mail provides end‑to‑end encrypted email that keeps both the subject line and message content private, ensuring that only the intended recipients can read the data. The service encrypts incoming external mail with the user’s keys on receipt, extending protection beyond communications between Skiff users. Users can manage their inbox with typical features such as compose, search, folders, and scheduled sending, while also customizing or linking a personal domain for a privacy‑first email address.

The platform is available as a web application and native clients for iOS, Android, and macOS, offering a consistent experience across devices. All code is open source, and the service is offered under a free tier, allowing anyone to adopt the software without cost. Its design emphasizes transparency and user control over data, positioning it as a private alternative to conventional email services.
