A global enterprise has onboarded multiple departments into isolated AWS accounts that are part of a unified AWS Organizations structure. Recently, a critical operational alert was missed because it was delivered to the root user’s email address of an account, which is only monitored intermittently. The enterprise wants to redesign its notification handling process to ensure that future communications - categorized by billing, security, and operational relevance - are received promptly by the appropriate teams. The solution should align with AWS security best practices and offer centralized oversight without depending on individual users. Which solution meets these requirements in the most secure and scalable way?
