On September 17, 2026, Simple & Easy Notification Service and Cloud Outbound Mailer were integrated into a single service and are now provided under the name Simple & Easy Notification Service.
After the integration of the 2 services, the Mail service is provided in the form of a project under Simple & Easy Notification Service, and the resources and task history of the existing Cloud Outbound Mailer service are migrated to Simple & Easy Notification Service.
The Simple & Easy Notification Service integrations guide explains the changes resulting from the service integration and precautions for using the service.
The Simple & Easy Notification Service user guide will be updated on an ongoing basis. After the service integration date of September 17, be sure to review the latest version of the guide.

Changes after the integration with Cloud Outbound Mailer
The following table compares the Cloud Outbound Mailer service before and after the service integration:
| Type | Before integration | After integration |
|---|---|---|
| Service location | Cloud Outbound Mailer (standalone service) | Within a Simple & Easy Notification Service project |
| Resource management | Cloud Outbound Mailer resource type | Simple & Easy Notification Service resource type |
| Pricing information | Cloud Outbound Mailer | Simple & Easy Notification Service (starting from the transition month) > MAIL |
| API | Cloud Outbound Mailer | Simple & Easy Notification Service API (integrated API). The existing Cloud Outbound Mailer API remains available for 12 months only for migrated projects. |
- The system automatically creates a Simple & Easy Notification Service project containing only the Mail service for existing Cloud Outbound Mailer customers.
- The automatically created project is assigned a random name in the
mail-UUIDformat. View the project name in the Simple & Easy Notification Service console. - The system migrates existing Cloud Outbound Mailer resources and task history to the automatically created Simple & Easy Notification Service project.
If you delete the project (mail-UUID) automatically created as part of the migration, you can no longer use the existing Cloud Outbound Mailer API.
- After deleting the project, only the new APIs available through Simple & Easy Notification Service can be used. If you are currently using the existing API, complete the transition to the new API before deleting the project.
- Cloud Activity Tracer service settings created based on existing Cloud Outbound Mailer resources may need to be updated after the integration.
- After the integration, be sure to verify that the permission scopes in the sub account permission policies are configured as intended.
Changes to Resource Manager
Following the service integration, resource information managed in Resource Manager changes as follows:
- The project resource for the Mail service is added as a Simple & Easy Notification Service resource.
- Existing Cloud Outbound Mailer resources and task history are migrated to Simple & Easy Notification Service.
- Resource NRNs, ResourceType names, and action names are changed to those used by Simple & Easy Notification Service.
- The Unsubscribe resource type in Cloud Outbound Mailer is removed.
If you have created a tracer in Cloud Activity Tracer based on Cloud Outbound Mailer resource types or actions, the tracer may not function properly after the integration. Therefore, update the tracer settings to use the applicable Simple & Easy Notification Service resource types and actions.
Changes to Sub Account
After the service integration, Cloud Outbound Mailer is provided as the Mail service of Simple & Easy Notification Service. Simple & Easy Notification Service controls permissions on a per-project basis, so permissions are migrated only for the projects created through the Cloud Outbound Mailer integration. (Separate from new projects)
Accordingly, for projects created through the Mailer migration, the corresponding Simple & Easy Notification Service permissions are automatically added to sub accounts that have existing Cloud Outbound Mailer permissions.
- Existing Cloud Outbound Mailer permissions are retained and not deleted.
- The Simple & Easy Notification Service permissions required to send, view, and change mail are added along with their related permissions.
- The automatically added permissions apply to the projects migrated from Cloud Outbound Mailer.
- Permissions that apply to all resources cannot be restricted by specifying a project, so the scope of permissions may be expanded.

Discontinuation of Cloud Outbound Mailer in the Singapore region
Cloud Outbound Mailer is discontinued in the Singapore Region effective September 17, 2026.
- After the discontinuation, Cloud Outbound Mailer is no longer available in the Singapore Region.
- If you currently use Cloud Outbound Mailer in the Singapore Region, switch to the Korea (KR) Region service before the discontinuation date. From September 17, the service is provided through Simple & Easy Notification Service.
- The KR Region operates in a separate environment, and migrating existing service usage records is difficult due to issues associated with cross-border data transfers.
After Cloud Outbound Mailer is discontinued in the Singapore Region, you can no longer access the email delivery history or resource information for that Region. Complete the transition to the Korea (KR) Region before September 17, 2026, to avoid service interruption.
