Configure Splunk Alert for Multiple Websites

I need a Splunk expert to set up a configuration for me. I should receive alert emails when multiple websites come back online after downtime. The alert emails should be customized to include the specific details: the website URL and, if available, the reason for the downtime.

Ideal skills and experience for the job:
- Proficiency in Splunk
- Experience with configuring website uptime alerts
- Ability to customize alert emails in Splunk
- Understanding of downtime causes and how to include them in alerts
