show new mail in main window

when new email arrives I would like it to show up in the main window, without me clicking on it

Hello, this is unfortunately not possible using current eM Client options. eM Client is unable to auto-read your email.

The application by default only synchronizes the message headers with the server, this option would have to automatically download the email, also I’m afraid this might also cause confussion, for example while you were reading your email in the main window.
