Skiff Mail
FreemiumPrivacy-first email with end-to-end encryption, custom domains, and integrated calendar, drive, and pages — now part of Notion.
What does this tool do?
Skiff Mail was a privacy-focused email service built on end-to-end encryption, meaning only the sender and recipient could read messages—not even Skiff's servers could access content. The platform bundled email with integrated calendar, file storage (Drive), and document creation (Pages), positioning itself as a privacy-first alternative to Gmail. Users could set up custom domains and received 10GB of free storage. However, the tool is functionally defunct: Skiff was acquired by Notion in February 2024, services were sunset on August 9, 2024, and the company only extended email forwarding through February 9, 2025. This means new signups are impossible, existing features are being dismantled, and users must migrate their data.

Advantages

Limitations
