Case Study: Intrum UK Limited

AI email agent automating 2,400 emails/month in 4 weeks

An autonomous AI agent built on AWS Strands Agents SDK and deployed to Amazon Bedrock AgentCore for Europe's largest credit management company. The agent reads every inbound email, classifies it, creates a structured case, and routes it to the correct team queue. FCA-compliant. Zero manual triage.

The challenge

Manual email triage at scale

Thousands of inbound customer emails each month, every one read and manually sorted by operations staff before it reached the right team. Skilled people spending hours on clerical sorting instead of resolving customer issues.

13 specialist teams, complex routing

Emails needed to reach the correct queue across 13 different teams, each handling distinct case types. Misrouted emails meant delays, re-work, and missed SLAs.

FCA compliance requirements

As an FCA-regulated business operating under Consumer Duty, every email classification decision needed to be auditable with full reasoning. Vulnerability indicators had to be flagged automatically.

No disruption to existing tools

The operations team used Microsoft 365 and Amazon Connect Cases daily. Any solution had to work with existing systems without requiring agent retraining or process changes.

What we built

A Strands Agent deployed to Amazon Bedrock AgentCore Runtime. The agent autonomously reasons about each email and chooses its own execution path. It is not a hardcoded pipeline.

01

Email ingestion and parsing

Inbound emails from the Microsoft 365 enquiry mailbox arrive via Amazon SES and are stored in S3. The agent extracts sender, subject, body, and all attachments (PDFs, Word, Excel, images, Outlook items) with full content extraction.

02

Autonomous classification

The agent reasons about each email and decides how to handle it. For emails with document attachments, it analyses the attachment content to determine specialist routing. It self-audits every classification before acting on it.

03

Structured case creation

The agent creates a fully populated Amazon Connect Case with typed fields covering category, priority, SLA deadline, team, vulnerability flags, and recommended next actions. Low-confidence classifications are routed to a supervisor queue for human review.

04

Audit trail and routing

Every classification decision is logged with full reasoning, confidence score, and routing outcome for regulatory retention. Each case is routed to the correct team queue. Human agents open a pre-triaged, pre-populated case and start resolving immediately.

Architecture

Strands Agent on Bedrock AgentCore Runtime. Serverless, session-isolated, with built-in observability.

Intrum email automation architecture Microsoft 365 enquiry mailbox flows through Amazon SES into S3 for long-term archival. An event-driven Lambda and SNS pipeline triggers a Strands Agent on Bedrock AgentCore, which autonomously classifies the email, creates a structured case in Connect Cases routed to the correct team queue, and writes a long-retention audit trail to Amazon DynamoDB.

Agent Runtime

Bedrock AgentCore

Strands Agent deployed to AgentCore Runtime. Serverless execution with session isolation, built-in observability, and consumption-based pricing.

AI Model

Amazon Bedrock

Claude foundation models via Bedrock. The agent uses a domain-tuned system prompt with self-audit verification on every classification.

Ingestion

Amazon SES + S3

Secure email intake with long-term archival. Every email stored before processing for FCA retention compliance.

Processing

Lambda + SNS

Event-driven classification pipeline. Deduplication, spam detection, and low-confidence flagging built in.

Case Management

Connect Cases

Structured cases with typed fields, routed to the correct team queue. Linked tasks as fallback. Customer profiles auto-created.

Audit Trail

Amazon DynamoDB

Every classification decision logged with reasoning, confidence score, and routing outcome. Long-term retention for regulatory compliance.

Infrastructure

AWS CDK

Infrastructure as code across three environments. Repeatable, auditable deployments.

Results

92% classification accuracy

The agent correctly classifies the large majority of inbound emails. Low-confidence decisions are automatically escalated to the supervisor queue with full reasoning visible.

50% triage workload reduction

Half of all manual email sorting eliminated. Operations staff now spend their time resolving customer issues instead of deciding where emails should go.

Per-email SLA tracking

The agent calculates and sets SLA deadlines per category, with shorter deadlines for regulated request types and standard timing for routine enquiries. SLA deadline is written as a typed field on every case, enabling real-time SLA monitoring across all team queues.

Real-time compliance checks

The agent detects vulnerability indicators at multiple severity levels and flags them on the case automatically. Regulated request types are surfaced for priority handling. Every decision is logged with full reasoning to a long-retention audit trail for FCA Consumer Duty compliance.

2,400 emails/month automated

Every inbound email processed in seconds. No backlogs. Urgent items surface immediately with the correct SLA and priority. Volume spikes handled without additional headcount.

Document-aware routing

The agent reads and analyses attachments across common document types (PDFs, Word, spreadsheets, images, Outlook items). The document content drives the routing decision, not just the email text, so specialist cases land with the right team automatically.
