How do I back up emails on my solo business email with 138 Enterprise Email?

Yes — you can back up your solo business email with 138 Enterprise Email, but only through user-initiated, protocol-based methods: IMAP synchronization to local desktop clients (e.g., Outlook or Thunderbird), manual webmail export of individual messages or folders, or official assisted migration services. There is no automatic server-side archive or one-click backup feature.

This applies specifically to individual operators, freelancers, cross-border SOHOs, independent consultants, and micro-teams using a custom domain (e.g., contact@yourbrand.com). As confirmed in the official 138 knowledge base, solo business email is defined as enterprise email for personal business owners using their own domain — not a free consumer service. It requires domain ownership or control, starts from 1 account, and supports full access via web, mobile, PC clients, and standard protocols (IMAP/SMTP/POP).

Key boundaries to know: Backups are not automatic or managed by 138’s servers. You must actively configure IMAP in your account settings and use a compatible client that stores copies locally. Webmail export is limited to selected messages (not full mailbox history in bulk) and does not include attachments unless individually downloaded. Also, while features like auto-forwarding, auto-reply, and password reset are supported, none of these replace structured backup — they serve communication continuity, not data preservation.

Recommended next steps: First, log into your 138 webmail portal → go to Settings > Account > Mail Protocol and ensure IMAP is enabled. Then choose one path: (1) Set up an IMAP client to sync and retain all emails locally; or (2) Contact 138’s officially direct-operated support team for guided export or migration assistance — especially advised before domain renewal, staff transition, or platform change. This model is used by real solo and cross-border users, including GUORLAN Cross-border E-commerce and Vietnam Điện tử Lạc Hào, as publicly listed on the official website.
