Hey trying to check what is an efficient way to solve this and what is the reason it occurs ? Is it because the email is not validated within the waterfall ?
(See red for error, green highlight for desired result/outcome)
When a waterfall continues running after finding an email, it's because the email found by a data provider failed validation.
The waterfall logic triggers the next provider to run when no email is found OR when the email found is invalid. This process continues until a valid email is found or all providers are exhausted.
To see validation details, unhide the validation columns in your table - they exist behind the scenes but are hidden by default. You can also adjust validation settings like treating catch-all emails as invalid if you want stricter validation.
