Built for privacy-focused users on Windows, this email client puts security and data protection first while keeping everyday workflows efficient. Strong encryption protects messages and attachments, and secure local storage with exportable backups helps preserve archives. Configurable account handling, per-account rules, and fine-grained permissions give administrators and power users precise control over message flow. Advanced filtering and customizable templates streamline repetitive tasks and speed up responses. The client handles multiple accounts and modern protocols with robust attachment management, fast search, and message threading so large inboxes remain manageable. Automation tools and batch operations reduce manual work for high-volume mail environments. Flexible layout presets, quick actions, and keyboard-centric controls let you tailor the interface to your workflow, while detailed logging and diagnostics aid troubleshooting. A companion Android app keeps users connected on the go, and comprehensive documentation and an active community make adoption straightforward for individuals and teams who prioritize private, reliable communication.

The Bat offers some cool features, but I had mixed feelings. The email organization is solid, but it sometimes crashes on me. I’m using it for now, but I’m not 100% sold on keeping it yet.
