%Net.MailMessage has an IsHTML property; set that to a value of 1 and you can use HTML in your WriteLine() calls to format your text.

Hi Blake,

This might get you started in the right direction:

Set tRuleName = "<rulename>"
Set tTarget = $ORDER(^Ens.Rule.Targets(tRuleName,""))
Set tArr = 0
Set tCnt = 1
While tTarget '= ""
{
    Set tArr(tCnt) = tTarget
    Set tTarget = $ORDER(^Ens.Rule.Targets(tRuleName,tTarget))
    Set tArr = tCnt
    Set tCnt = tCnt + 1
}

Replace <rulename> with the name of the rule as it appears in the router configuration pane.

Sorry, I was never able to solve this before I finished up with that client. If I have some time I will experiment with one of my local environments.
