Case Study: AI Email Automation Reduces Customer Service Workload by 60%

How a Major Automotive Parts Distributor Transformed Their Customer Support with Intelligent Automation

---

The Challenge

A leading OEM automotive parts distributor was drowning in customer service emails. With thousands of monthly inquiries about order status, part compatibility, pricing, and shipping—their small but dedicated customer service team was spending over 30 hours per week responding to the same questions repeatedly.

Key Pain Points

• Volume Overload: 5,000+ customer emails monthly; 70% repetitive questions
• Slow Response Times: 8-12 hour response delays
• Scaling Issues: Hiring couldn’t keep up
• Team Burnout: Too much time on mundane tasks
• Lost Revenue: Delayed responses → abandoned orders

The Solution

We designed and deployed a custom AI-powered email automation workflow that intelligently handles routine customer inquiries while seamlessly escalating complex issues to human agents. The system integrates directly with the client's existing Replyco helpdesk software via API to retrieve incoming emails.

What We Built

• Replyco Integration: Automated retrieval of customer emails via Replyco API
• Internal AI Email Application: Built with Python, Litestar, and Postgres for intelligent parsing and response generation
• Intelligent Email Classification: Uses GPT-4 to categorize and prioritize incoming emails
• Automated Escalation & Routing: Webhooks via n8n coordinate between Replyco, the AI application, and GPT-4 for seamless workflow
• Smart Escalation Protocol: Complex emails flagged for human agent review

Technology Stack

• Replyco Helpdesk Software (API) - for email retrieval and ticket management
• Python with Litestar - internal AI application framework
