excellent file sharing point – regular update online and e-mail notifications to stockholders

I am very new in sharing point. I've created a team share point and I'm downloading an Excel file containing actions. I also put the names of the owners of the action. Now, I want these owners to be informed of the actions so that they receive an email with a link and that they access the Excel link online and update their status on the actions. after their update is registered, I will receive an email. How am I doing this?
