# Trial Ending Soon: Track Expiring Trial Alerts

> Count trial ending soon events to identify conversion opportunities. Track users approaching trial expiration for targeted outreach.

<Tip>
  Trial Ending Soon counts the total number of times a trial was flagged as approaching expiration, typically within a defined window before the trial ends.

## Formula

<Info>
  **Trial Ending Soon** = **COUNT** ( trial\_ending\_soon events )

| **trial\_ending\_soon events** | Individual instances when a trial enters the ending-soon window |

| Metadata        |                         |
| --------------- | ----------------------- |
| **Type**        | Number                  |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Count                   |

## Example

Your SaaS product flagged **1,420 trials ending soon** in Q1, triggering conversion workflows.

| Month        | Ending Soon | Converted Before Expiry | Extended | Expired |
| ------------ | ----------- | ----------------------- | -------- | ------- |
| January      | 460         | 184                     | 46       | 230     |
| February     | 480         | 202                     | 53       | 225     |
| March        | 480         | 211                     | 48       | 221     |
| **Q1 Total** | **1,420**   | **597**                 | **147**  | **676** |

## How It Works

The Upstack Pixel fires when a trial enters a predefined warning period before expiration, typically 3-7 days. This event triggers conversion workflows, reminder emails, and sales outreach. It helps identify users who need intervention before their trial expires without converting.
