Secure Enterprise Email Free Trial: Domain Setup, Security Validation & Real-World Readiness

Who This Guide Is For

This is a decision-ready implementation guide for IT administrators, foreign trade operations leads, and small-to-midsize team managers in China who need to evaluate whether 138 Enterprise Email meets actual deployment requirements — not just feature checklists. It reflects documented conditions across publicly listed cases: China Railway, GUORLAN Cross-border E-commerce, Vietnam Điện tử Lạc Hào, and Japan Hirose — all using the service for secure, domain-based communication with global partners.

What the Trial Requires — Not What It Offers

The 138 Enterprise Email free trial is purpose-built for realistic readiness assessment. It is not a generic demo account. To begin:

• You must use your own custom domain
• (e.g., `@yourcompany.com`) — no trial access is granted on shared or free domains. As confirmed in official FAQ: “Enterprise email uses customer-owned domains as the `@` suffix.”
• Identity verification is mandatory: enterprises submit business license documentation; individuals complete ID verification per current compliance requirements.
• Activation timing depends on readiness: *“If domain and documents are complete, activation typically takes 1 working day; if domain registration is needed, it takes 1–2 working days.”

Security Features You Can Validate — Before Committing

During the trial, you can directly configure and observe enterprise-grade protections — not just read about them:

• Sender authentication: Full support for SPF, DKIM, and DMARC record publishing via admin portal — essential for preventing domain spoofing and improving inbox placement with international recipients.
• Spoofed email identification: Built-in alerts for suspicious senders appear in the webmail interface — validated in real use by Guo X Law Firm and cross-border sellers like GUORLAN.
• Recoverable operations: Administrators can restore deleted emails within 7 days, and recover user accounts deleted within the same window — both explicitly documented in official help resources.

Critical Prerequisites — Verify These First

What the Trial Does Not Cover — Clear Boundaries

• No subdomain trials (e.g., `@test.yourcompany.com`) unless explicitly verified and delegated.
• No automated migration from Gmail, Outlook, or other providers — full mailbox migration requires post-trial coordination with 138’s official operations team.
• Trial accounts are capped at ≤5 active users unless pre-approved — aligning with the official minimum of “1 account starting point”.
• No SLA-backed uptime or incident response — this is an evaluation environment, not production service.

Real-World Suitability Check

Ask these three questions before proceeding:

• Do you communicate regularly with clients or partners in Vietnam, Japan, or ASEAN markets?*
• → Confirmed delivery nodes and public cases (Điện tử Lạc Hào, Hirose) validate regional reliability.
• Do you require centralized control over passwords, device access, and data recovery?*
• → Admin portal supports forced password resets, multi-device sync (web/mobile/PC/third-party IMAP/SMTP), and 7-day mail/user recovery.
• Is your industry subject to audit or regulatory review?*
• → Platform references alignment with Ministry of Public Security Multi-Level Protection Scheme Level 3, National Information Security Evaluation EAL3+, and National Confidentiality Technology Evaluation — verify original certificates before scaling.

Next Step: Begin With Operational Clarity

If your domain is verified and DNS access confirmed, start the official trial process through 138’s direct-operated portal. All configuration, migration, and daily O&M support is handled exclusively by Shenzhen 138 Computer Technology Co., Ltd. — no agents, no intermediaries. This ensures consistency, accountability, and direct escalation paths — a key differentiator confirmed across public deployments including China National Gold Group and China CNR.
