Tuta Mail is a secure email service that provides end-to-end encryption for emails, contacts, and calendar entries across all devices.
The service addresses the challenge of communicating securely by building encryption directly into its platform rather than treating it as an optional feature. Users can send encrypted messages to anyone without requiring recipients to use Tuta Mail itself, and all data stored on Tuta's servers remains encrypted. The tool is built in TypeScript and uses the Mithril framework, with clients available as web applications, desktop software, and mobile apps on iOS and Android.
Tuta Mail suits users and organizations prioritizing privacy in their email communications, particularly those handling sensitive information who want encryption enabled by default rather than as a manual step. The service operates as a complete email provider rather than a plugin or add-on, meaning adoption involves switching to Tuta's infrastructure. The project maintains a public roadmap and directs feature requests through Reddit and support channels rather than GitHub issues.
The project has established a clear contribution policy that excludes pull requests or issue reports generated with assistance from large language models, though it welcomes incomplete or manually translated contributions. Development discussion and bug reports are routed through a dedicated Reddit forum rather than GitHub's issue tracker. The codebase is maintained with active attention to the distinction between human-authored and AI-assisted submissions.
