The Simple One-Way Email Notification profile is another type of Email Notification profile that can be setup to notify people when alarms occur. This one-way email notification profile is just as the name suggests, one way. It listens for active alarms within a given priority range, and when the alarm criteria is met, it sends alarm notifications via email to a specified On-Call Roster.
Although it's similar to the Email Notification Profile, it does not utilize Alarm Pipelines and does not include a link in the Email message to allow recipients to acknowledge the alarm.
It is important to be aware that there is no way to filter which alarms get sent using this notification profile other than the priority, so if alarms are sent to the same roster through an alarm pipeline, users may see duplicate alarms.
