Flectar Mail is a lightweight, native home for your email, calendars, and contacts. It is engineered to open instantly, stay responsive, and use a fraction of the memory of a typical web-based mail client. Measured on Linux with one IMAP account (860 messages), the inbox open and an HTML newsletter displayed, 60 seconds after launch, with the default CPU renderer. Private memory is what Windows Task Manager lists as Memory. On Windows, with 7 real accounts and about 69,000 unread messages, Task Manager shows about 40 MB with the window open and about 4 MB once it's closed to the tray. See how we measure and how to check it yourself. Flectar Mail renders email with Blitz, a Rust HTML/CSS renderer from the Dioxus team, instead of embedding a browser or WebView. If a message renders incorrectly, please report it. Read more about the renderer and the CPU and GPU…
