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.

🔵 Section 2: Specialist Agents

Each is powered by GPT-4.1-mini (cheaper + faster).

  • 🔍 Prospect Research Specialist → researches target companies, roles, pain points.
  • ✍️ Cold Email Copywriter → drafts subject lines, hooks, and persuasive body copy.
  • 🎯 Personalization Specialist → inserts custom variables for each recipient.
  • 📅 Email Sequence Strategist → designs follow-ups, timing, nurture flows.
  • 📬 Email Deliverability Expert → ensures emails land in inbox, not spam.
  • 📊 Outreach Analytics Specialist → tracks performance, runs A/B tests, optimizes campaigns.

💡 Why useful?

  • Each agent is a specialist → just like a real marketing team.
  • Parallel execution in n8n means faster results.
  • Modular → you can remove or add more specialists.

🟣 Section 3: Execution Flow

  1. Request comes in via chat trigger
  2. Director (O3) interprets and delegates → calls specialists as tools
  3. Specialists generate their pieces (research → copy → personalization → sequence → deliverability → analytics)
  4. Director integrates results into a cohesive cold email campaign

🟡 Section 4: Documentation & Notes

There are two Sticky Notes inside the workflow:

  • Header Note → Support info + tutorials (YouTube & LinkedIn by Yaron Been)
  • Main Note → Full documentation (overview, use cases, cost optimization, tags)
