Email notifications now use BCC for multiple recipients
When you send Grafana-managed alert email notifications to multiple recipients (without the “Single Email” option), Grafana Cloud Alertmanager now uses BCC instead of TO headers by default. This means individual recipient addresses are not visible to other recipients in the same notification, and the TO field is empty.
If your workflow depends on inspecting the TO header of alert emails, contact Grafana Support to have BCC disabled for your instance.
