Also, if you want that trigger to send you email, you will need to turn on Database Mail (DBMail) in order to use it.
To get you started, here is a simple script to send a message, once DBMail is turned on and set up.
@profile_name = 'SQL Server Agent Mail Profile', -- this should be the actual profile name you give it when set up

@subject = 'This is only a test' ;
