Cost
Risk

Regulatory/compliance exposure (DPDP/GDPR where applicable) and reputational damage if transparency, fairness, and escalation controls are insufficient.
Executive Report
HDFC Banking Support Email Transformation: Hybrid RAG + Agent Triage and Response Copilot
HDFC is managing ~50,000 support emails per month with an average customer response time of ~48 hours, creating dissatisfaction, escalation risk, and inconsistent handling. We recommend a Hybrid solution combining retrieval-augmented generation (RAG) with an orchestration (Agent) layer to automate triage, prioritization (including fraud/disputes), routing, and compliant first-draft responses with human-in-the-loop controls. This approach is designed to reduce standard-query SLA to <8 hours and high-priority SLA to <2 hours while maintaining banking-grade security, auditability, and policy-grounded responses. Within the ₹25 lakh budget, a focused pilot followed by controlled rollout can automate triage for ~80–90% of emails and provide agent-assist drafting for ~40–60% of emails, driving ~25–35% handling-effort reduction and fewer repeat contacts. The operating model emphasizes strict PII controls, prompt-injection defenses, deterministic routing guardrails, and measurable governance to satisfy regulatory and internal audit expectations.
