Valids are not getting passed on in the waterfall to the work email column - also it should be passing catch all too but it doesnt seem to be, thanks - https://share.zight.com/p9uyBDYk
This issue typically occurs when emails are found but fail validation. When a provider finds an email that doesn't pass validation (either marked as invalid or catch-all when you've toggled "Only mark 'Safe to Send' emails as valid"), the waterfall continues to the next provider instead of passing that email to the final column.
By default, catch-all emails are treated as valid, but if you've enabled the "Only mark 'Safe to Send' emails as valid" option, catch-alls will be excluded.
To troubleshoot, unhide the validation columns to see the detailed validation steps and understand why specific emails aren't making it to the final column.
