Database Performance Metrics: These include CPU usage, memory usage, and disk I/O. Monitoring these metrics can give you insights into how your database is performing. Query Performance: Analyze the performance of the queries run during your email campaigns. Slow queries can be optimized to reduce load. Connection Pooling: Ensure that your application is efficiently using database connections, which can help in managing load effectively. Automated Alerts: Set up automated alerts to notify you of any unusual spikes in database activity. Scalability: Regularly assess whether your current database setup can handle the increasing load as your email list grows.
