A possible option here is to create a dashboard that contains the list of alarms:
- Save your custom alarm filter (Working with saved alarm filters)
- Create a dashboard and add an alarm table component
- After selecting the alarm table, go to Settings
- In Filters select Saved Filter
- Select the filter that you created
- Using an automation script (or scheduled task) you could send an email including the dashboard created in the previous step.
Hope it helps!
