Datadog uses Amazon Simple Email Service (SES) to send password reset emails and other important messages. To ensure high trust in these communications, they use a managed service from their cloud provider and leverage Datadog's Log Management product for observability. They create an SNS topic that triggers a Lambda function whenever an email event is generated on Amazon SES. The Lambda function transfers the email event to Datadog Log Management. This setup allows easy access to email-related metrics, which helps support teams troubleshoot login issues and provide better assistance to customers.
