I Sent 75,000 Cold Emails Last Month Using Claude (Here's How)

In this video, I show how I used Claude to manage a full cold email operation, from building lead lists to adding contacts into Smartlead campaigns and tracking performance. I break down why AI agents only work when you already have a clear process, then show how tools like AI Arc, Smartlead, MCP connectors, and Slack can turn outbound into a much smoother system. I also walk through how to set up daily campaign reports, deliverability checks, and automated analysis so you can see what is actually working without manually checking everything every morning. By the end, I show the real campaign results from sending around 75,000 cold emails in May 2026, including new leads and interested replies.

Overview

How to Scale Cold Email Operations with AI Agents

In this video, Wesley Hoang shares his blueprint for managing an outbound cold email operation that successfully sent 75,000 emails in May 2026. By leveraging Claude as an intelligent AI agent, he automated lead generation, campaign execution, and performance analysis.

Core Strategy for AI-Powered Outbound (0:00 - 2:53)

The AI Employee Mindset: Treat your AI agent like a new hire by providing two critical pillars: access to your tools and training on your specific processes. AI enhances existing systems rather than replacing missing ones (1:11 - 2:38).
Tool Stack: To build this system, connect your AI to:
- AI Arc: A massive B2B database with over 400 million contacts (2:53 - 3:15).
- Smartlead: The engine for campaign warm-up, inbox rotation, and deliverability (3:15 - 3:27).
- MCP (Model Context Protocol): The bridge that allows Claude to interact directly with these tools without manual data entry (3:46 - 4:17).

Workflow Automation & Maintenance (5:19 - 11:45)

Lead Management: Automate the sourcing of verified leads using Claude + AI Arc, ensuring all emails go through verifiers like BounceBan to maintain high deliverability (5:19 - 6:46).
Reporting: Replace manual daily spreadsheet updates with automated Slack reports generated by Claude. These reports include campaign stats, interested lead counts, and bounce metrics (7:41 - 9:42).
Deliverability Audits: Schedule monthly checks where Claude identifies underperforming domains and automatically proposes swaps with warm backup inboxes (10:19 - 11:29).

Campaign Results (11:45 - 12:49)

By implementing this automated infrastructure, the operation achieved:

75,000 Total Emails Sent in May 2026.
47,000 Net New Leads reached.
Approximately 300 Interested Replies, demonstrating the scalability of an AI-managed outbound process (11:45 - 12:27).
