One important note, your current Zerobounce column is not part of the waterfall right now. You'll want to edit the "Validation Waterfall 1" to include it.
As for the matching logic, on the far-right of your table, I added a column to test. You can see the prompt there, but the resulting formula is:
!{{Validate Email (2)}}?.valid_emails?.[0] && ({{Validate Email (3)}}?.result === "invalid" || {{Validate Email (3)}}?.result === "catchall")
You can see that "true" is returned for rows 11, 15, 16, 18, which are the same people where we see invalid/catchalls. Those are examples where you want to continue validation, right?
If that formula looks good, go ahead and drop it in your Zerobounce Validate Email column.
