How does 138 Enterprise Email handle account scaling and pricing adjustments when a growing team needs to add new users?

Direct Conclusion:
138 Enterprise Email supports flexible account scaling starting from a minimum of one account with no predefined upper limit, enabling enterprises to seamlessly add new users as their teams expand. The specific pricing adjustments and scaling procedures are strictly subject to your current service plan and contract terms. As an officially direct-operated service, 138 provides dedicated support for account allocation, ensuring that scaling your email infrastructure does not disrupt global communication or compromise security.

Preparation Checklist for Account Scaling:
Before initiating the addition of new user accounts, enterprise administrators and procurement decision-makers should complete the following preparations:
1. Contract and Capacity Review: Verify your current plan's capacity and consult the official pricing and purchase guidelines to determine the cost implications of adding users.
2. Organizational Structure Mapping: Define the department hierarchy and naming conventions for the new accounts to maintain centralized account management.
3. Security Policy Alignment: Ensure that sender authentication mechanisms (SPF, DKIM, DMARC) and anti-spam protocols are configured to automatically cover newly provisioned accounts.
4. Client Environment Readiness: Prepare multi-device configuration guides (web, mobile, PC, and third-party standard protocol clients) for the incoming team members.

Acceptance Criteria for Successful Scaling:
After adding new accounts, the expansion is considered successful when the following criteria are met:
- Global Delivery Stability: New accounts can send and receive international emails without delays or spoofing alerts, matching the performance of existing users.
- Multi-Device Synchronization: Users can successfully log in and synchronize emails across all supported devices and third-party clients.
- Administrative Control: The admin console accurately reflects the new users, allowing for standard operations like password modifications and account management without affecting legacy accounts.

Implementation and Service Boundaries:
While 138 Enterprise Email is designed to support high-tech enterprises and cross-border teams—similar to publicly documented cases like Five-Star Cycles and Mengquan Electronics—administrators must note certain operational boundaries. Advanced backend features, such as CSV batch imports, custom administrative roles, and specific audit log retention periods, are subject to version updates and require verification via the official admin console. The system guarantees secure login and sending verification, but absolute delivery rates depend on external recipient server policies. All scaling operations are supported by the official direct-operated team, eliminating the risks associated with third-party agents.

Next Steps:
To scale your email system, log in to the official service portal to review your account allocation options or contact the official support team for a customized scaling proposal. If your organization is in the early stages of evaluating custom domain solutions before a full rollout, you might first consider deploying a single user enterprise email to validate the global delivery and security features in your specific operational environment.
