Multi-Agent Cold Email Campaign Generator with O3 Director & GPT-4.1 Specialists

🌍 Overview

This workflow simulates a virtual sales & marketing team where each AI agent has a role:

A Director Agent (O3) who manages strategy.
Multiple Specialist Agents (GPT-4.1-mini) for research, writing, personalization, deliverability, sequencing, and analytics.
Everything is triggered automatically when a new chat message request comes in.

🟢 Section 1: Entry & Director

🔗 Nodes:
1️⃣ When chat message received (Trigger)
💬 Starts the workflow when a new request arrives (e.g., “Create a cold email campaign for SaaS CTOs”).

2️⃣ Outreach Director Agent (O3 model)
🎯 The “manager” agent. Decides what kind of campaign is needed and assigns tasks.

3️⃣ Think (Planning Node)
🧠 Helps the Director structure thoughts before delegating.

💡 Why useful?

Director uses O3 (strong reasoning model) only where strategy is needed → reduces cost.
Provides a single point of control to coordinate all other agents.
