# Setting Up CloudWatch Alarm Notifications ## Overview Domain expertise for configuring Amazon CloudWatch alarm notification channels using Amazon SNS topics and subscriptions. Covers creating encrypted SNS topics, setting up subscriptions for email, SMS, and webhook endpoints, configuring topic policies for CloudWatch access, and linking alarms to notification actions. ## Set up alarm notifications To configure notification channels for a CloudWatch alarm, follow the procedure exactly. See [CloudWatch alarm notification setup procedure](references/setup-cloudwatch-alarm-notifications.md). ## Troubleshooting ### Email notifications not received Verify the email subscription was confirmed. Use `aws sns list-subscriptions-by-topic` to check that the subscription status is "Confirmed" rather than "PendingConfirmation". ### SMS notifications failing Ensure the phone number is in E.164 format (e.g., +12345678901) and that SMS is supported in your AWS region. ### Alarm not triggering notifications Verify the alarm has the correct SNS topic ARN in its AlarmActions using `aws cloudwatch describe-alarms`, and ensure ActionsEnabled is set to true.
