🔖 Feature description

The idea would be that a user can "Subscribe" to a status page and get notifications for any changes in status. This way an anonmous user can setup alerts for the status page.

Jira's Status page has this functionality

✔️ Solution

Add an option to subscribe to service status on the public status page to a non-registered user

❓ Alternatives

Adding many alerts or using a webhook to an external service, but there isnt a clean soultion

📝 Additional Context

Not sure, if you need anything else LMK
