By default, Clay considers catch-all emails valid in the email waterfall process. If you're not seeing catch-all emails in your results, check if you have the "Only mark 'Safe to Send' emails as valid" option enabled - this setting excludes catch-all emails.
For specific providers like Icypeas or Prospeo, make sure the "Include catch-all email results" toggle is switched on.
To view catch-all emails found by the email waterfall:
1. First, unhide the validation columns by opening the Columns Panel - these are hidden by default.
2. Once visible, you can filter your table to show only catch-all emails by using these validation columns.
By default, Clay considers catch-all emails valid in the waterfall process, so they'll appear in your final results unless you've toggled on "Only mark 'Safe to Send' emails as valid."
