I never bothered with trying to get any detail out of the email message. Once I got a text stating my alarm had been activated, I would log directly into a) the Elk app and/or b) my camera system.
My camera system was configured to send me MMS messages as soon as anyone was at my front door, so I would typically always get those before any alarm message anyway. So, for example, I would see my wife walking through the front door, then get a message that the alarm was going off... likely due to some excuse relating to needing to do something else and forgetting to disarm.
