How the n8n Lead Verification Pipeline Works
Pre-configured with industry deliverability rules: ingest leads → verify sub-second via API → branch based on deliverability.
Inbound Webhook
Receives raw contacts exported from Apollo, Clay, Google Maps scraping bots, or website opt-in forms.
Field Normalization
Extracts email, first name, and company fields dynamically regardless of payload structure.
MailVeri API Check
Sub-second probe evaluates MX records, syntax, throwaway domains, and live TLS SMTP handshakes.
Deliverability Split
Routes VALID leads straight into Instantly/Smartlead, while quarantining risky or invalid addresses.
