Transact SQL :: Create Alert Email From Query

How can I turn this query into an Email alert if one of the counts are GT 50. The Source are machines that I capture counts(Unprocessed_Cntr) from every 5 minutes and load to the Load_Time_Capture table. I also add a datetime to each capture(Unprocessed_Capture ).  

If any individual source has a count > 50 or if the combined(ALL) GT 50 send an email to support person.  

SELECT 
 CASE GROUPING([Source])
                  WHEN 1 THEN 'ALL'
                  ELSE [Source] END AS 'Input Source',           
                 avg([Unprocessed_Cntr]) as 'Average Queue Past 15 Min' 
                                      
FROM        Load_Time_Capture
WHERE Unprocessed_Capture >=  DateADD(mi, -15, Current_TimeStamp)
GROUP BY    [source] WITH ROLLUP
