Yes, that is the code block for a UE server behavior.
dont copy it, create the other 2 instances of the server behavior.
Webassist -> Create Email Message
to create the emails for each category, then add the if statement around the UE server behaviors so the correct one triggers depending on the category.
If you need further assistance with this, I Would suggest signing up for a premiere support appointment:
