I am extremely new to Kentico world and i just want to use Kentico to to send mail on creating new document to admin who manage document node and sending mail to document creator after approving or rejection of the document. I search on documentation to find how to do so but i can't figure out how.

I successfully configured email parameters but i don't know how to tell the system when and which one it will going to send the mail.

Any help will be appreciated.
