Triggering e-mail in the script

Hi Experts,

     I am new to SAP CLM. I have some questions about the triggering notification e-mail to user. Can you please guide me on the following question.

1. I have an extension collection. I would like to send an e-mail to users when the user add new row to extension collection. Is it possible to trigger the e-mail to the user in the script? Can you give me the example code for the triggering email?
2. I have an extension collection to collect the reviewers of the Project Document. I would like to have somethings like scheduled task to send the email to remind the reviewer in the extension collection. Is there any way to do this requirement?

     Could you please guide me how to do the above requirement. Thank you in advance.

Thank you,

Noppong Jinbunluphol
