You might have mapped these 4 variables values to one of the fields of your target table.
Lets assume this record producer is for incident creation.
So trigger you email when an incident is created and include the fields in your email which you used in record producer mapping.
Another option is to create a JSON (or any other string format) form the variables and their vales in record producer script (using producer.variable_name) and then trigger an event passing this JSON as parameter.
On the notification select this event and then use the email script to parse this JSON and add in the body or to populate subject.
But please note that in this case if the incident is not creates for any reason in the backend (which is rare) even then the email will be triggered.
If not these 2 then you need to find where the record producer variables and their values submitted are stored
