How do I turn off emails sent when a page is created or edited?

You are receiving emails when a page is created or edited because there is a workflow setup to do this

  1. In the “Library” section go to “Settings” in the top menu
  2. Then choose “Workflows
  3. In the list there will be “Page created” and “Page edited”
  4. You can either disable, delete or edit the action to your requirement
