Notification Email Not Coming

Hi,

I have created a Repository and enabled subscription for its folder.My repository has all the required Services like Subscription,tbl,serviceACL and properties.

When i create a document thru KM ,i get the mail of the file being created.But when i programatically copy and paste files from a folder to my Repository folder then i dont get any notification Email.

I want to get a Notification Email when i prgramatically copy files from a temporary folder to the Repository folder.

Could some one pls help me on this.

Regards
