Powerful Dead Letter Management, Built for DevOps

Everything you need to find, fix, and prevent Azure Service Bus dead letter issues. From AI-powered investigation to real-time alerts.

Real-Time Dashboard

See your dead letter queue health at a glance with live updates.

Your command center for dead letter management. The dashboard gives you instant visibility into queue health, recent activity, and messages requiring attention across all your Azure Service Bus namespaces.

Dashboard features:

  • Live message counts See dead letter counts update in real-time across all your queues
  • Namespace overview Monitor all connected namespaces from a single unified view
  • Queue health indicators Quickly spot which queues need attention with visual status indicators
  • Activity feed Track recent actions and new dead letters as they happen

AI-Powered Investigation

Find related failures across your entire system in seconds, not hours.

When a dead letter appears, you need to know: is this a one-off, or part of a bigger problem? DeadLetterOps uses AI to analyze message content, headers, and metadata to find similar failures across all your namespaces and queues.

How it works:

  • Semantic similarity matching Finds messages with similar meaning, not just exact text matches
  • Cross-namespace search Searches across all connected Azure Service Bus namespaces
  • Pattern detection Identifies common failure patterns like timeouts, serialization errors, and validation failures
  • Root cause suggestions AI analyzes the error and suggests likely causes and fixes

Message Details & History

Full visibility into every dead letter message and its journey.

Every detail you need to understand and fix the problem. DeadLetterOps captures the complete message state and maintains a full audit trail of everything that happens to it.

Inspection capabilities:

  • Complete message inspection View message body, headers, custom properties, and system metadata
  • Dead letter reason See exactly why each message ended up in the dead letter queue
  • Message history tracking Track every action taken on a message: requeues, edits, and deletions
  • Exception details Full stack traces and error information when available

Advanced Filtering

Find the messages you need instantly with powerful search and filters.

When you have hundreds of dead letters, finding the right ones matters. DeadLetterOps provides powerful filtering and search capabilities to help you focus on exactly what needs attention.

Filter options:

  • Filter by queue or topic Narrow down to specific queues, topics, or subscriptions
  • Time-based filtering Find messages from specific time ranges or relative periods
  • Content search Search within message bodies and properties
  • Error type grouping Group messages by dead letter reason or exception type

Batch Operations

Stop processing messages one at a time. Handle up to 100 messages in a single action.

When an incident creates dozens or hundreds of dead letters, you need to act fast. DeadLetterOps lets you select multiple messages and requeue or delete them all at once.

Batch capabilities:

  • Bulk requeue Send up to 100 messages back to their original queue or an alternate destination
  • Bulk delete Remove messages that are no longer needed
  • Smart selection Filter and select messages by error type, time range, or content pattern
  • Edit before replay Modify message content or headers before requeuing

Real-Time Slack Notifications

Know about dead letters the moment they happen, not when customers complain.

Connect your Slack workspace and get instant notifications when new dead letter messages arrive. Stay informed without constantly checking the dashboard.

Alert features:

  • Instant Slack notifications Get alerted in the channel of your choice within seconds
  • AI-powered summaries Notifications include AI analysis of the error and suggested actions
  • Direct links One-click from Slack to the message in DeadLetterOps

Issue Buckets

Organize related failures and maintain a clear audit trail.

Group related dead letter messages into issue buckets. Perfect for tracking incidents and maintaining an audit trail of how failures were resolved.

Organization features:

  • Create issue buckets Group related messages by incident, root cause, or any criteria
  • Full audit trail See who did what, when - every requeue, delete, and status change is logged

MCP Assistant Integration

Manage dead letters from Claude Code, ChatGPT, or any MCP-compatible assistant.

DeadLetterOps is the first dead letter management platform with native Model Context Protocol (MCP) support. Query, analyze, and fix dead letters without leaving your terminal or IDE.

What you can do:

  • Natural language queries "Show me all failed orders in the last hour"
  • AI similarity search "Find similar payment failures"
  • Bulk operations "Requeue all timeout messages to the retry queue"
  • Analytics on demand "What namespaces have the most failures today?"

Deep Azure Service Bus Integration

Built specifically for Azure Service Bus, not a generic message queue tool.

DeadLetterOps understands Azure Service Bus at a deep level. We support queues, topics, and subscriptions with all their nuances - dead letter reasons, transfer dead letters, scheduled messages, and more.

Azure Service Bus support:

  • Queues, topics, and subscriptions Full support for all Azure Service Bus entity types
  • Multiple namespaces Connect and monitor multiple namespaces from one dashboard
  • Dead letter reason tracking See exactly why each message was dead lettered
  • Message metadata View all properties, custom headers, and system metadata
