# Health monitor

> Track customer risk, monitor recovery, and act on health issues with workflow interventions.

Health monitor helps you detect risky customer behavior early, apply fixes faster, and measure outcomes like users recovered and revenue protected.

## What it does

* Surfaces health risk trends from signup, purchase, and activity signals
* Highlights segments that need intervention
* Connects each issue to a recommended action path
* Tracks impact after action

## Core health metrics

Use these metrics as your baseline operational view:

* Revenue at risk
* At-risk users percentage
* Failed payment impact
* Re-engagement recovery rate
* Dormancy trend (30/60/90 days)
* Activation rate
* Time to first value
* Active user health trend
* Trial-to-paid conversion quality

## Action loop

Health monitor is most useful when your team follows a repeatable loop:

1. Detect issue: identify high-risk cohorts and trend changes.
2. Diagnose cause: check lifecycle tags, activity drops, and payment outcomes.
3. Choose fix: use a recommended workflow path.
4. Execute safely: approve and launch intervention.
5. Measure result: track saved users and protected revenue.

## Required inputs

To keep health metrics reliable, make sure these inputs are active:

* Event ingestion for `signup`, `purchase`, and `core_activity`
* Tag updates for health-related states
* Workflow execution and outcome tracking
* Basic account settings (timezone, sending windows, limits)

## Recommended workflows for health interventions

Common health interventions are mapped to predefined workflows. Start with:

* Low usage alerts
* Re-engagement reminders
* Final attempt win-back
* Satisfaction and check-in workflows

See the workflow library here:

* [Workflow Library by State](/documentation/core-functionalities/workflows/predefined-workflows-by-state)

## Operational best practices

* Review health metrics on a fixed cadence (daily or weekly)
* Prioritize cohorts by potential revenue impact
* Keep intervention windows short and measurable
* Compare outcomes before and after each intervention cycle
