You have a couple of options to preview a message before it's sent: 1) do a test run 2) add a human-in-the-loop step 3) "create a draft" instead of sending In this demo, we showed (1) and (2), but (3) is sometimes useful as well!
It is possible actually! We didn't have a chance to cover it in this video, but you can set up a "Role" that is populated from Notion and use that Role as the sender of the automation in our "Run As" menu. We'll be sure to include that in a follow up video on more advanced usage.
