Automating blocking a contact and deleting a message in Mail app

If I select an Apple Mail Message and right click it, a pop up appears with several choices including **Block Contact** and **Delete**. I'm trying to create a little Automator and/or AppleScript routine that will do both to a selected message, but I don't know where to find the AppleScript commands to tell Mail what to do other than **tell** *application* "Mail".
