Overview
A Los Angeles–based wholesale manufacturer and supplier of promotional products needed a way to keep up with tens of thousands of customer emails every month, without burning out its seven-person inside sales team.
Working with HatchWorks AI, they implemented an AI-powered email automation system that reads every incoming message, identifies which ones truly need responses, pulls real-time order data from NetSuite, and drafts accurate replies directly in Microsoft Outlook.
The result: nearly half of response-worthy emails are now handled automatically, giving the sales team more time to focus on complex, high-value customer requests.
The Challenge
The company’s inside sales team is the front line for customer communication.
Each month, they receive tens of thousands of emails from distributors and resellers, ranging from simple “What’s my order status?” questions to complex, custom requests.
Over time, the team’s bandwidth was increasingly consumed by:
- Repetitive order-status questions
- Routine policy clarifications (shipping, returns, timelines)
- Low-value notifications that didn’t actually require a response
The impacts were clear:
- Limited capacity for complex requests. High-value, nuanced customer inquiries competed with repetitive emails for attention.
- Rising operational strain. Manually triaging and replying to thousands of emails was exhausting for the seven-person team.
- No baselines for improvement. The company lacked clear visibility into which emails required human responses, what could be automated, and how accurate automation would be.
The company needed an automation solution that could:
- Automatically handle high-volume, repeatable questions
- Maintain brand tone and accuracy
- Integrate with Outlook and NetSuite
- Give leadership real metrics on coverage, accuracy, and adoption
The Process
HatchWorks AI partnered with the company to design and implement an AI-powered email automation engine built around four key components: classification, response generation, quality verification, and user feedback.
- AI-Powered Classification Engine
The first step was determining which emails should be automated at all.
- Built an email classification engine on Google Cloud Platform (GCP) leveraging OpenAI to read each incoming message.
- Classified emails into “in-scope” categories suitable for automation (e.g., order status, shipping timelines, policy clarifications).
- Identified “out-of-scope” messages that required human attention (e.g., custom orders, escalations, edge cases).
This classification layer ensured that AI only touched the types of messages where automation could be both safe and valuable.
- AI Response Engine in n8n
Once in-scope emails were identified, HatchWorks AI implemented a multi-agent workflow using n8n:
- The n8n workflow connected to NetSuite to fetch order details such as status, shipment dates, and relevant policy information.
- An OpenAI node in n8n generated draft responses based on the structured data and the original email content.
- Responses were formatted to match the company’s brand voice and support expectations, then surfaced directly in users’ Microsoft Outlook inbox.
This created an end-to-end flow where the system could understand the question, pull relevant data, and construct a customer-ready reply.
- LLM-as-Judge Quality Verification
To maintain trust, the team implemented an additional guardrail:
- A dedicated “LLM as a judge” step was added within the n8n workflow.
- This verification layer evaluated each AI-generated response against quality criteria such as relevance, completeness, and clarity.
- Only responses meeting the quality threshold were delivered to users
This quality gate helped ensure that automation drove efficiency without sacrificing user experience.
- User Feedback Module & Adoption Analytics
To make the system better over time, HatchWorks AI implemented a user-facing feedback loop:
- Internal users could quickly signal whether an AI-generated response was helpful or needed improvement.
- Usage and adoption metrics were captured to understand:
- How often AI was triggered
- How frequently responses were accepted versus edited
- Where additional training or policy refinement was needed
This closed-loop feedback allowed the company and HatchWorks AI to continuously fine-tune prompts, classification logic, and response patterns based on real-world performance.
The Outcome
The AI-powered automation system gave the company measurable gains in both efficiency and insight.
- 47% automation coverage for emails that genuinely required responses.
- Clear visibility that nearly 50% of incoming emails did not require any response at all; they were purely acknowledgements, system notifications, or marketing messages.
- Up to 70% “send-ready” responses for routine inquiries, with a built-in review path for edge cases.
- A reusable automation framework that can be extended to new email categories, policies, or product lines over time.
The inside sales team now spends less time on repetitive status checks and more time on complex, relationship-driven work that improves customer satisfaction and drives revenue.
- Decision-Ready Email Automation
By integrating Outlook, NetSuite, OpenAI, n8n, and GCP into a cohesive solution, the company and HatchWorks AI transformed email from a bottleneck into a strategic asset.
The system now:
Classifies every incoming email and routes it appropriately.
Automatically generates accurate, context-aware responses to routine inquiries.
Surfaces real-time performance metrics around coverage, accuracy, and adoption.
Rather than guessing how much of the inbox could be automated, the company now operates with data-backed insights, and a proven system that’s already handling a substantial portion of support load.
