# View interactive report runners

> **Note:**
> The feature is experimental and will be further developed in future releases.

Use the `REPORT_RUNNER_EMAIL` environment variable to view the emails of those viewers who run interactive reports (initiators). This information can help you, as a report owner, modify the content of your report based on which user is viewing or running it. For example, you can change the options available in the interactive controls used in the report, or hide certain categories from the tables provided in it.

Cases of when the `REPORT_RUNNER_EMAIL` environment variable is populated are different in the On-Premises and Cloud versions of Datalore.

| On-Premises | Cloud plan | Cloud Free plan |
| --- | --- | --- |
| For all types of authorized users:     * Report owner    * Regular type user    * Viewer type user   | For certain users:     * Team owner    * Team member   | For one user type only:     * Report owner   |

To access the environment value, you can use the `os` module:

```PYTHON
import os
os.environ.get('REPORT_RUNNER_EMAIL')
```
