Webhook Link: Open 'On form submission' and copy the Test URL to your form settings.\n2. Credentials: In 'Neverbounce: verify an email', select your NeverBounce API key.\n3. Logic: The 'If' node is set to valid. Add catchall if you want to be less restrictive.\n4. Error Handling: If an email is invalid, the 'Form - Invalid' node triggers a retry screen for the user.\n5. Success State: The 'Form - Success' node displays your \"Thank You\" message after a valid submission.\n6. Final Step: Replace 'Create Lead in CRM' with your actual CRM node (HubSpot, Salesforce, etc.).\n\n\n## Video Tutorial:\nWatch the 75-second setup guide above\n@[youtube](FDy-eaITcAQ)"
