Automate Lead Verification in n8n.
Stop Burning Outbound Domains.
Plug MailVeri into your n8n pipelines in 30 seconds. Verify leads from Webhooks, Apollo, or Clay in real time, auto-quarantine dead mailboxes, and route only deliverable contacts to Instantly or Smartlead.
How the n8n Lead Verification Pipeline Works
Pre-configured with industry deliverability rules: ingest leads → verify in real time 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
Real-time probe evaluates MX records, syntax, throwaway domains, and live TLS SMTP handshakes.
Tri-Route Deliverability
Routes VALID leads to Google Sheets & Instantly, holds risky CATCH_ALL leads for Slack review, and quarantines dead emails.

Frequently Asked Questions
Common questions about running MailVeri inside n8n Cloud and self-hosted workflows.
Does this workflow work on both n8n Cloud and self-hosted n8n Community Edition?
Yes. The MailVeri n8n workflow template uses only standard built-in nodes (Webhook, Set, HTTP Request, and Switch), so it imports cleanly into both n8n Cloud and self-hosted Docker/Community instances (v1.0+).
How do I handle large batches of leads in n8n without hitting rate limits?
In n8n, you can either use the Loop Over Items (Split In Batches) node with the HTTP Request node for real-time streams, or submit files up to 1,000,000 rows via the MailVeri Bulk API and receive a completion callback directly on an n8n Webhook trigger.
Does MailVeri also offer a native MCP server for n8n AI Agent nodes?
Yes. In addition to standard HTTP Request nodes, MailVeri provides a hosted Model Context Protocol (MCP) server (https://mcp.mailveri.com/mcp) that n8n AI Agents can call autonomously before sending emails.
