Hi,

email script only has access to current object and not previous. 

you can't access previous value in email script if you didn't call the email notification via gs.eventQueue() method

you can use after insert/update BR and use gs.eventQueue() approach and send the previous value

Then use that in email script

Example:

BR -> I am sending previous assigned to name in parm2

(function executeRule(current, previous /*null when async*/) {

	// Add your code here
	gs.eventQueue('eventName', current, current.assigned_to, previous.assigned_to.name.toString());

})(current, previous);

Then in email script use this event.parm2 to get that value

(function runMailScript(current, template, email, email_action, event) {

	// Add your code here

	template.print('Previous Assigned to user is: ' + event.parm2);

})(current, template, email, email_action, event);
