Email alerts from Monitors -- plaintext vs Image

I may be missing something, but if I set up an email notification for a Monitor, is there a way I can customize the BODY using variables and have it delivered as text?

It seems that the Body of the email notification comes to me as an IMAGE.  This makes it entirely useful for intended plan to parse various content from the body of the alert. 

Is this really the only option for notifications from Monitors???
