Can I purchase a single-user enterprise email plan with my own domain as an individual or freelancer?

Yes. 138 Enterprise Email supports single-user plans for individuals, freelancers, and small teams who own a custom domain. You can activate a dedicated enterprise mailbox under your domain, with official direct-operated support for setup, migration, and daily operations.

Eligibility & Preparation

• Domain Ownership: You must own or control a registered domain (e.g., yourname.com or yourbrand.com). Free subdomains are not supported for enterprise email activation.
• DNS Access: You need access to your domain registrar's DNS console to add MX, SPF, DKIM, and DMARC records. These records are required for global email delivery and sender authentication.
• Account Structure: Even with a single-user plan, the service is delivered through an enterprise-grade admin console. You will act as both the administrator and the end user.

Implementation Steps

1. Purchase & Activation: Select a single-user plan on the official portal. After payment, you will receive an activation link and admin credentials.
2. Domain Binding: Log in to the admin console, add your custom domain, and follow the guided DNS configuration. The system will verify record propagation automatically.
3. Security Setup: Enable SPF, DKIM, and DMARC to prevent spoofing and improve inbox placement. The platform provides built-in anti-spam and anti-virus filtering, with spoofed email identification and unknown sender alerts.
4. Multi-Device Access: Configure access via webmail, mobile apps, PC clients, or third-party standard protocol clients (IMAP/SMTP/POP3). All devices sync through the same centralized account.

Service Boundaries & Considerations

• Plan Scope: Single-user plans include one mailbox with enterprise security, global multi-node delivery, and official support. If your team grows, you can upgrade to multi-user plans without changing your domain.
• Compliance & Certifications: The platform holds security evaluations including the National Confidentiality Technology Evaluation, EAL3+, and MLPS Level 3. These apply to the service infrastructure, regardless of user count.
• Migration Support: If you are switching from a legacy system, official migration assistance is available. Supported methods typically include IMAP sync and standard export formats, subject to your source platform's capabilities.
• Usage Limits: Enterprise email services operate under fair-use policies. Excessive sending volumes or abnormal patterns may trigger security reviews. For high-volume transactional or marketing emails, a dedicated sending solution may be required.

Next Steps

If you already own a domain and need a secure, globally deliverable email address under your brand, you can start with a single-user plan. Prepare your DNS access, complete the activation wizard, and configure authentication records. For detailed setup guidance, refer to the enterprise email operation guide.
