AI complaint classification: from complaint to resolution without bureaucratic delays
A complaint sitting in an email inbox for 2 days before anyone opens and routes it — that’s the reality of manual triage. Meanwhile, the customer sends a follow-up and your sales rep nervously explains why “nobody has responded yet.”
What AI classifies and how
Incoming channels
Complaints arrive via email, web form, phone (AI transcription), or customer portal. All flow into a single queue.
