Running an email waterfall enrichment and had a question about validation. I want to use ZeroBounce to validate emails found in waterfall using the HTTP API since it is cheaper and can also give me a “catch-all” confidence score. However, I was wondering how I would set it up in the waterfall so that when Zerobounce runs, if it is returned as “catch-all” then I can have it give me a confidence score, if it is greater than 8 we keep the email and mark as verified, if it is 7 or less then we move onto the next email finder in the waterfall. Is that possible?
Hey, Sean W. Run ZeroBounce validation on the email using their HTTP API. Check the result: If result is valid Keep and mark as verified. If result is catch-all Check the confidence score (zerobounce_score) If score > 8 Keep and mark as verified. If score ≤ 7 Move to the next email finder in your waterfall. If result is invalid, unknown, or spamtrap Skip and move to the next finder.
Sean W. Yes, you can use a waterfall approach for email enrichment and validation Try Provider A → If email found, validate it → If valid, stop If not, try Provider B → validate stop if valid Repeat until success How to do it Automation tools (Zapier, Make, etc,) Use IF/ELSE conditions. Code: Use a loop with early exit after success. CRM workflows: Use conditional branches.
