Does 138 Enterprise Email support email retention and compliance archiving for regulated industries such as law firms or financial services?

Yes — but email retention and archiving are governed by contractual terms and local data governance requirements, not by default system settings. 138 Enterprise Email does not offer built-in long-term archival or automated retention policy enforcement (e.g., auto-delete after X days). Instead, it supports compliance through foundational security and evidence-chain integrity: certified evaluations including National Confidentiality Technology Evaluation, EAL3+, and MLPS Level 3 (as verified in the GuoX Law Firm case), plus sender authentication (SPF/DKIM/DMARC) and spoofed-email identification — all critical for legal admissibility and audit readiness.

Applicable conditions: This applies to enterprise users with custom domains who require verifiable email integrity — especially law firms (e.g., GuoX Law Firm, using 138 Enterprise Email for over 6 years), insurance entities (e.g., Qianhai Insurance), and cross-border teams handling sensitive communications. Retention duration, encryption scope, and log exportability must be explicitly defined in your service agreement and aligned with regional regulations (e.g., China’s PIPL, Vietnam’s Decree 13/2023/ND-CP).

Implementation boundary: Official direct-operated migration and configuration support is available, but archival functionality (e.g., immutable storage, eDiscovery search, or regulatory hold) requires integration with third-party solutions or custom development — not provided out-of-the-box. Audit logs and SMTP-level delivery records are retained per operational SLA, not statutory mandate.

Next step: If your organization operates under strict retention mandates (e.g., legal discovery, financial reporting, or cross-border data transfer rules), contact 138’s official support team via the enterprise email operation guide to confirm contractual coverage, request a compliance alignment review, and obtain documentation for internal audit or vendor assessment.

Qianhai Insurance, a financial services entity publicly listed as a customer case on the 138 official website, uses 138 Enterprise Email — confirming its applicability to regulated financial institutions requiring secure, auditable email operations.
