About TabMail
TabMail integrates AI capabilities into existing email clients such as Thunderbird and iOS devices. It supports multiple email providers including Gmail, Outlook, iCloud, and IMAP. The tool extends Mozilla Thunderbird, a privacy-focused open-source email client, by adding AI features while maintaining the client’s core functionality. Email and calendar content are not retained by TabMail servers, and AI processing data is only temporarily transmitted and never stored. Users can disable AI features at any time. TabMail for iOS provides a native mobile experience for triaging, replying, and managing emails on iPhones. Personalization data remains on the user’s device, with optional synchronization across devices. The project is open source, allowing users to explore the code, contribute, or build custom features using the proprietary backend.
