Resolved
Grafana Labs has taken steps to safeguard the Grafana Cloud platform against the distribution of unauthorized emails. We have implemented the following changes to new Grafana Cloud Free and Trial accounts, effective immediately:
Users who open Grafana Cloud Free and Trial accounts can only send email alerts and reports to users within their Grafana instance. Other email recipients will be rejected. Additionally, the Cloud Alertmanager is no longer available for these instances, requiring all alerting to be configured via the native Grafana Alertmanager. All other integrations for alerting remain functional.
If users would like to expand their email capabilities, they can upgrade their Grafana Cloud account to scale their use case, as needed.
These changes to alerting and reporting will be applied to all new Grafana Cloud Free and Trial accounts. Existing Grafana Cloud Free and Trial accounts opened before April 20 and all other Grafana Cloud account types are unaffected by these changes.

Update
Grafana Labs is implementing measures to safeguard the Grafana Cloud platform against ongoing unauthorized use while preserving the capabilities relied upon by our community. Effective immediately, we have made the following modifications to the platform:
Alerting
Email alerting has been disabled for new Grafana Cloud Free and Trial accounts; however, all other integrations such as webhooks remain functional. Additionally, Cloud Alertmanager is now disabled for Grafana instances in these accounts, requiring all configuration to occur via the native Grafana Alertmanager. Existing Grafana Cloud accounts remain unaffected by these restrictions and all other Grafana Cloud account types are also unaffected.
Reporting
To prevent the distribution of unauthorized emails, Grafana instances in new Grafana Cloud Free and Trial accounts are limited to sending reports exclusively to users within their Grafana instance. Standard reporting functionality continues unrestricted for existing Grafana Cloud accounts and all other Grafana Cloud account types.
We remain committed to further refining platform security to ensure a safe and open environment for our entire user base.
