When creating escalations for a response level, you often want to send the same sort of title and message body out at various points. To save time, get one set up with all the symbolic references in it, test etc and then copy/paste into your system options to included the title and detail you have so lovingly created. This replaces the automatic text and title the system normally generates. Now create your new escalation messages and your new text with placeholders will be copied through. This also gets the messages consistent and saves editing all of them later.
PS if you have turned on HTML email, put in some <br> type text markers so the email doesn't come out as one big long line.
