[development] sending automated email using views

Hello I was looking for a way to send a notification for all users who flagged a node (using the flag module) i can get all of the users through views but am looking for an automated way to notify them about the updates on this node by sending them email is there a module that do such a thing I've seen the views email module but it's not automated and it's really complicated and hard to use i was planning to create a module that will use actions and triggers to send automated emails for user list generated through views but i wont to make sure if there is something ready out there thank you.
