Schedule email reports and configure threshold based-email alerts using Amazon QuickSight

Amazon QuickSight is a cloud-scale business intelligence (BI) service that you can use to deliver easy-to-understand insights to the people you work with, wherever they are. You can build dashboards using combinations of data in the cloud, on premises, in other software as a service (SaaS) apps, and in flat files. Although users can always view and interact with dashboards on-demand in their browser or our native mobile apps, sometimes users prefer to receive notifications and report snapshots…
