Thunderbird is no different than Electron apps, though. It's built on a browser engine, renders UI written in HTML + CSS (+ XUL partially), consumes ~500MB of RAM on idle, etc.
That's because thunderbird is a full featured application. It contains a browser because you can actually use that browser. It's not using the browser as a mere presentation engine.
