Alerting: Grafana Cloud uses the internal Alertmanager for Grafana-managed alerts by default

In Grafana Cloud, the internal Grafana Alertmanager handles Grafana-managed alerts by default.

New stacks use internal routing by default. Sending to an external Alertmanager isn’t enabled by default.
Existing stacks move to internal routing by default, plan by plan. If your stack actively sends to an external Alertmanager, it keeps that configuration and continues to work.

Sending Grafana-managed alerts to an external Alertmanager is still supported. If you need it, contact Grafana Support.

To learn more about Alertmanager options, refer to Configure Alertmanagers.
