Delete email without opening

Searched but didn’t find an answer: Is it possible to delete an email message within Em Client without opening it? I know images are often blocked, but many people would prefer the message never be displayed.

When right-clicking a message in the inbox list (to select Delete), the message is immediately rendered. I’d like to see the email rendered on mouse-up, instead of mouse-down, and it should wait for the results of the right-click menu.

Similarly, if I want to drag a spam message to the trash, it should never render the unwanted message, instead remaining on the currently rendered email.
