How to show full query results in a SQL alert's notification?

I have a SQL alert; the code behind it looks like this:

SELECT COLUMN_1, COLUMN_2, COUNT(*) AS TOTAL, 1 AS FORCE_TRIGGER
FROM MY_TABLE
GROUP BY COLUMN_1, COLUMN_2

The idea is that a scheduled job updates my_table and then runs the alert. The alert triggers when MIN(FORCE_TRIGGER) > 0 (in other words, each time it runs). It then sends me a notification via email with the query results included via the variable @QUERY_RESULT_TABLE.

The alert runs successfully and sends me an email. However, in it I only get a single row of query results.

Does anyone know how to get the full query results to display in the email please?
