AI Email Classification and Routing at Global Scale

Executive Summary
A top shipping and logistics enterprise unified fragmented customer service mailboxes and automated email routing with AI. The program moved from manual triage to intelligent classification inside the client's CRM, lifting accuracy to 80-97 percent, speeding response, and standardizing service across regions. Business coverage reached 95 percent of global activity.
The solution transformed customer service operations across 28 agencies worldwide, creating a unified, efficient, and scalable email management system.
Business Challenge
Fragmented Email Management
Multiple mailboxes per agency created manual routing work and misrouted emails, leading to customer frustration and operational inefficiency.
Regional Inconsistency
Inconsistent handling between regions and lack of standardization resulted in varying service quality and customer experiences.
Slow Response Times
Manual processes caused slow response and reduced customer satisfaction, impacting business relationships and competitive positioning.
