What to Prepare Before 138 Enterprise Email Expires: A Maintenance Checklist for IT Admins

Why Email Expiration Catches Teams Off Guard

A common failure scenario: a foreign trade team in Shenzhen discovers on a Monday morning that all outbound emails to overseas clients are bouncing. The domain's MX records are intact, but the 138 Enterprise Email service tied to that domain has expired over the weekend. No renewal was processed, and the admin contact listed on the contract has since left the company.
This is not a rare edge case. For enterprises, cross-border e-commerce operators, and small teams relying on custom domain email, service expiration can halt communication, break client trust, and expose historical data to deletion. Because 138 Enterprise Email operates on an officially direct-operated model—without intermediary agents—the responsibility for tracking renewal timelines and preparing continuity measures falls squarely on the enterprise IT administrator or the designated business owner.
Below is a structured checklist of what to prepare before your 138 Enterprise Email subscription expires, based on the platform's actual service conditions and administrative boundaries.

1. Confirm Domain Ownership and DNS Access

Your 138 Enterprise Email service is bound to a custom domain. Before expiration, verify the following:

• Domain registration status: Ensure the domain itself (e.g., `yourcompany.com`) is not expiring before or shortly after the email service. A lapsed domain invalidates all email routing regardless of the email subscription status.
• DNS management access: Confirm that your team still holds login credentials for the domain registrar or DNS provider. You will need this access to maintain or reconfigure MX records, SPF, DKIM, and DMARC records during renewal or migration.
• Administrative contact accuracy: If the domain's administrative contact email or phone number points to a former employee, update it immediately through your registrar.

Boundary note: 138 Enterprise Email requires a domain that the customer owns and can manage. If you do not currently hold a domain, one must be registered first—official support can assist, but domain pricing, ownership, and renewal terms are separate from the email service contract.

2. Back Up Emails, Contacts, and Account Data

Once a subscription expires, account access and data retention follow specific platform rules. Based on 138's documented administrative boundaries:

• Deleted account recovery window: Administrators can restore deleted user accounts within 7 days of deletion. After this period, recovery is not guaranteed.
• Deleted email recovery: Only administrators can restore deleted emails for sub-accounts, and the publicly documented window is also within 7 days of deletion.
• Export before expiration: Use the webmail interface or a standard protocol client (Outlook, Foxmail) configured via IMAP/POP to export critical mailboxes and contact lists before the service lapses. This is especially important for cross-border teams whose client correspondence may have legal or compliance significance.

Actionable step: Assign an IT team member to perform a full mailbox export for all active accounts at least 14 days before the expiration date. Store exports in a secure, accessible location.

3. Audit Active Accounts and Licenses

Before renewing, review your current account structure:

• Active vs. dormant accounts: Identify accounts belonging to former employees. Administrators can delete accounts through the
