Connect HubSpot: In the 'Get many contacts' node, connect your credentials and select the specific list or search criteria for the contacts you want to audit.\n\n3. Neverbounce credentials: In 'Neverbounce: verify an email', select your NeverBounce API key.\n\n4. Configure Flagging: In the 'Hubspot: flag risky contact' node, ensure the 'Lead Status' mapping aligns with your internal HubSpot properties (currently set to mark 'valid' as 'Open' and others as 'Disqualified').\n\n5. Final Report: Connect your Slack credentials in the 'Slack final audit report' node and choose the channel where you want the summary audit sent after the loop finishes.\n\n\n## Video Tutorial:\nWatch the 53-second setup guide above\n@[youtube](NZU8s1cnIJI)"
