Service Disruption Notice
Use this notice for outages, degraded performance, or critical service changes that affect customers now. Say what is affected, when the issue began, and where users can follow updates. Replace the sample status details and support links, then send a resolution message once service is restored.
Loops
Include the next update
Set an owner and a time for the next update before sending. Link to a status page that can stay current after the inbox copy becomes stale, and avoid promising a resolution time you cannot support. Send it as transactional email, not a marketing campaign, even when it goes to every customer. Unsubscribed contacts still receive transactional email, and a service notice is classified by its purpose, not its audience size.
