1) Basically this will notify you no matter what happens. If the test passes successfully you probably won't need to even look at the log but you will still get an email. If the test fails for any reason at all (if any step shows up as Failed) you will also receive an email.
2) This will send out an e-mail only if a "normal" error is encountered. By normal error I mean an error that's related to the HTML/Silverlight/WPF app that's under testing (missing controls, wrong text values etc.)
3) This will send an e-mail only if there was test failure not related to the actual app that's under testing. e.g. the Execution server on the intended machine might be switched off.
