The new logs histogram in the Courier dashboard provides a real-time visual overview of message activity, making it easier to diagnose issues and track trends. With this feature, users can instantly spot spikes in failures or drops in message volume, zoom into specific periods for further analysis, and view an instant visual overview of message activity over time. The histogram offers a more secure way to authenticate AWS SES using IAM Role authentication, eliminating long-term access keys and reducing security risks. Additionally, Courier customers are unaffected by Apple's APNS Security Update, which requires updated server certificates starting on March 29, 2025. Users can send up to 10,000 notifications every month for free with the Courier service.
