Greetings!  We recently rolled out communities and upon case closure we have created an email template that sends an email alert to the customer that the case has been closed.  Within that email alert we have an embedded link to a Survey Monkey survey that we ask the customer to complete.  The link comes across in the email just fine and the customer is able to complete the survey.  However, all of the identifying fields that also are embedded within that link such as CustN={{{Organization.Id}}}&ContFN={{{Recipient.FirstName}}}&&ContLN={{{Recipient.LastName}}}&ContEm={{{Recipient.Email}}}&T={{{Case.CaseNumber}}}&A={{{Sender.Alias}}}&P={{{Case.Product__c}}} are not being passed over as expected to Survey Monkey. 

If we manually send an email with the link via email within the case record it is working and populating all fields as expected.  What are we missing with respect to the email alert?  We don't want our support reps having to remember to send this communication manually.
