CAD offers customers three different options for alerts: 1/ Immediate alert via SNS channels, 2/ Daily summary via email, and 3/ Weekly summary via email. We believe daily email alerts is the best option and cadence for new customers. Weekly may be too delayed to provide sufficient value as a standalone alert; many customers and immediate alerts require an SNS channel that we do not have for accounts by default. After CAD is turned on, customers can change their alert preference at any time.
