Send email notification on rule firing

Summary:

Is it possible to send an email notification with BML?

Content (required):

We have an advanced rule that returns true when a required parameter is missing. I am looking for a way to send a notification when that rule fires and returns true. The email would go to someone responsible to correct that requirement, so that the transaction can be processed.

I thought the easiest way would be to send an email by adding to the advanced rule BML that does the check for that parameter.

Thank you for any suggestions.
