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.
