T-SQL (SS2K8) :: Trigger And Email Notification

I have created a trigger like this below:

CREATE TRIGGER TriggerName ON Table_Name AFTER INSERT AS
DECLARE @SERVICE varchar(40)
DECLARE @STATUS varchar(3)

SET @SERVICE=(SELECT [SERVICE] FROM inserted)
SET @STATUS=(SELECT [STATUS] FROM inserted)

[Code] ....

When I added some a new record to Table_Name with Status='X' nothing happened. I have tried to exec only script below:

EXEC msdb.dbo.sp_send_dbmail @recipients=N'moj_adres', @body= 'test', @subject = 'Subject!!!!', @profile_name = 'profil'

and I received email notification.
