# Inspector

> Inspector helps you understand how messages are delivered to individual users. Use it to QA campaigns, troubleshoot delivery behavior, and explain outcomes with confidence.

## Before you begin

* [At least one Agent](https://docs.hightouch.com/ai-decisioning/agents.md)

## Overview

**Inspector** (labeled **Experience inspector** in the app) helps you understand how messages are delivered to an individual user.

Instead of aggregated metrics, Inspector shows *exactly what happened* for a specific person—step by step—across one or more agents. This makes it easy to validate campaign behavior and explain outcomes with confidence.

In Inspector, you can review a user’s **full journey across agents**, including:

* When the user becomes eligible for an agent
* Which messages were evaluated and which were sent
* When sends were skipped, including by smart suppression
* Which content and variants were selected

Inspector is most useful during **campaign setup, QA, troubleshooting, and reviews**, when you need to confirm that agents are behaving as expected for real users.

It complements [**Insights**](https://docs.hightouch.com/ai-decisioning/insights.md), which focuses on performance trends and lift across many users, by providing a clear, user-level explanation of delivery behavior.

## Navigate to Inspector

In the Hightouch app, go to:

`AI Decisioning` > [`Inspector`](https://app.hightouch.com/ai/inspector?from=docs)

From here, you can:

* Filter by **All agents** or a specific agent
* Search for a user
* Step forward or backward between users
* Review each user’s experience over time

## Review a user’s experience

Inspector is organized into three main areas that work together to explain delivery behavior.

### User attributes

The left panel shows the **full set of user attributes available to agents**.

These attributes help explain:

* Eligibility and agent entry
* Message selection and personalization
* Suppression or exit behavior

This view represents the broader user context agents can use when evaluating decisions across the user’s journey.

![User attributes list](https://mintcdn.com/hightouch-3c037897/L_vQfA0JQEpeGUUo/images/ai-decisioning/inspector/aid-inspector-user-attributes.png?fit=max\&auto=format\&n=L_vQfA0JQEpeGUUo\&q=85\&s=b108265b7f535fe5d54f53345b0c2f88)

> [!NOTE]
>
> The attributes shown here represent **everything the agent knows** about the
> user. Not every attribute directly influences every message decision.

### Experience timeline

The center panel shows a chronological timeline of the user’s journey across agents.

You may see events such as:

* **Eligible for agent**
* **Wait periods** between evaluations
* **Messages sent**, including channel and agent
* **Skipped sends**, including smart suppression
* **Exited agent** events
* **Outcome events**, such as clicks or purchases (when available)

This timeline makes it easy to understand both **what happened** and **what didn’t happen**, in context.

### Message details

To open the message details drawer, open the actions menu on a message card and select **View message** or **View data payload**, or click the message thumbnail.

This view explains **what was sent** and shows the **data behind it**.

![View message button](https://mintcdn.com/hightouch-3c037897/L_vQfA0JQEpeGUUo/images/ai-decisioning/inspector/aid-inspector-view-message.png?fit=max\&auto=format\&n=L_vQfA0JQEpeGUUo\&q=85\&s=13aff047de5f78b275a89f6e7622da32)

The drawer includes two tabs:

| Tab | Purpose |
| - | - |
| `Preview` | View the rendered message content as delivered to the user (when supported). |
| `Data` | Inspect the payload sent to the destination, including variables and metadata. |

Use these views together to validate content and confirm the variables and personalization sent to the destination.

## When to use Inspector

Use Inspector when you need a **clear, user-level explanation** of how an agent behaved for a specific person.

Inspector is best suited for questions like:

* *Why did this user receive this message?*
* *Why was a send skipped or suppressed?*
* *What personalization and variables were sent with the message?*
* *How did this user’s experience unfold across agents?*

Common scenarios include:

| Scenario | How Inspector helps |
| - | - |
| QA a new agent | Preview upcoming messages and confirm eligibility before launch |
| Troubleshoot skipped sends | Identify smart suppression, wait periods, or exit conditions |
| Validate personalization | Confirm the variables and content sent to the destination |
| Review user journeys | See how experiences unfold across multiple agents |
| Stakeholder reviews | Walk through real user examples to explain outcomes |
