vb or sql server generate email message

Question

In a change to a .net 2010 application that uses a sql server 2012 database, I am thinking of using a trigger when a duplicate record has been generated. This trigger would send outlook 2013 or office 365 email message to selected users. I am thinking of doing this instead of having the duplicate record email message sent out in the .net application. Thus would you show me the code  and/or point me to a url that will show me how to accomplish my goal?
