What is Flectar Mail?
Flectar Mail is a native Rust application for managing email, calendars, contacts, and files. It connects to Gmail, Outlook, Microsoft 365, and services using standard mail and synchronization protocols. Mailboxes and calendars are stored locally so synchronized data remains accessible offline. Profiles, account colors, conversation threads, and tabs help organize personal and work accounts.
The application uses Blitz to render email HTML and CSS without an embedded browser or WebView and without executing message scripts. Remote images are blocked until permitted. Preview downloads are available for Windows, macOS, Linux, and Android, alongside a source build option. The product is not yet stable, and its experimental renderer may display complex messages incorrectly.

Key capabilities

- Message privacy Blocks remote images by default and renders email without executing scripts or embedding a WebView.

Where Flectar Mail fits
Flectar Mail fits personal and work email workflows that combine multiple accounts with calendars, contacts, and offline access. Its import tools support migration from Thunderbird, K-9 Mail, Apple Mail, and supported mailbox formats. Before migration, users should test account synchronization, representative HTML messages, and backup handling against their existing workflow.
Deployment requires checking the alpha build's platform restrictions and authentication setup. Gmail and Outlook sign-in need a bundled OAuth registration or the user's own application keys. Linux requires a Secret Service keyring; Windows previews are unsigned, macOS previews are not notarized, and the Android release APK is a test build. Updates are installed manually.
