To find the in-app impression rate, we need to add two Measures to the Messages Look.
- Go to Reports » Performance Analytics and select the Messages Dashboard.
- For the Messages Look, click and select Explore from here.
- In the sidebar, go to Message Metrics » Measures » In-App Impression Metrics and click next to:
- In-App Impression Rate
- In-App Dismissed User Rate
- Click Run.
If you want to drill down to a view where you can export user IDs, click the user count or rate within the returned data, then click Run again. See: Exporting Lists.
