Send an alert email without displaying it to operators

I want to send out an email when an alert goes active, but I want the alert indication to be hidden from the operators in their alarm list. What is the best way to do this?

there is a few ways I would imagine. 1 would be setting it to a low severity and not including that low severity in the query that fills the alarm summary.

2 would be making a separate tag that looks at the tag in questions value. make sure that tag is filtered out by system/path.

It really just depends on the architecture of your system.

Not sure if this would fit what you wanted, but you can also send emails using scripting, so instead of using an alert you could write a tag change script on the gateway to evaluate the value and send the email.
