Question : SQL AFTER UPDATE TRIGGER

I have a table named stockm which contains product information. In this table is a coloum named analysis_c which is updated to say DELETED when a product is discontinued.
I have been asked if this information can be auto emailed out whenever a product changes. the coloums I need to email are product, description, analysis_c and Shipping_catergory.

I have looked into this and found out about the AFTER UPDATE trigger. I have never used triggers in sql before so could some one please explain to me how they work with an example so i have an idea where to begin.

Thanks
