AI-Powered Email Automation System
Case Study Summary
Role: AI Engineer Company: Sala Scala - The Wise Dreams Industry: Enterprise AI Solutions
Impact Metrics:
- Reduced daily email triage from 100+ items to 10-15 actionable items
- Automated classification and prioritization of incoming communications
- Production system deployed and serving real users daily
- Presented as Technical Speaker at Datamecum Webinar 2025
Challenge
The client was drowning in a high volume of daily emails — over 100 items requiring manual review, classification, and response. The manual triage process was time-consuming, error-prone, and diverted skilled professionals from higher-value tasks. They needed an intelligent system that could automatically understand email content, classify urgency, and surface only the items that truly required human attention.
Approach & Architecture
I designed the solution as a production workflow, not just a classification demo:
- Structured output layer with Pydantic-AI so the system returns validated, type-safe decisions instead of free-form text.
- RAG classification pipeline to ground decisions in domain-specific context, policies, and historical examples.
- FastAPI service layer for real-time email processing and clean API integration with surrounding systems.
- Deterministic orchestration to keep routing and prioritization behavior consistent across categories and edge cases.
The architecture followed hexagonal principles so the LLM layer, business rules, and infrastructure could evolve independently.
Results
- Daily email triage reduced from 100+ items to 10-15 actionable items
- Automated classification with high accuracy across multiple categories
- Real-time processing with sub-second response times
- System deployed to production and serving daily workloads
- Scalable architecture ready for multi-tenant deployment
Tech Stack
- Pydantic-AI for structured LLM outputs
- RAG pipeline for context-aware classification
- FastAPI for RESTful API endpoints
- Python backend services
- Docker containerization
- Hetzner cloud infrastructure
- Hexagonal architecture for maintainability
This project was later presented as a technical talk at Datamecum Webinar 2025, showing the production architecture, design decisions, and operational results.
