How do I connect my own domain to a solo business email account so I can send and receive mail under my brand?

Direct answer: To use your own domain with a solo business email, you must own a manageable domain, purchase a 138 Enterprise Email plan that starts from one account, and configure the required DNS records (MX, SPF, DKIM, and optionally DMARC) at your domain registrar. Once DNS propagates and the system verifies the records, your branded address (e.g., name@yourdomain.com) becomes active for sending and receiving.

Prerequisites and preparation:

• Domain ownership: You need a domain registered under your name or business entity. 138 Enterprise Email requires a customer-managed domain as the @ suffix; the service cannot create a branded address without one. If you do not yet have a domain, registration must be completed first. Domain pricing, ownership structure, and renewal terms should be confirmed before purchase.
• Account planning: Decide your primary address format (e.g., your name, contact@, sales@, or service@). The administrator creates accounts within the purchased quota. Additional accounts can be added later; fees and pro-rata calculations follow the current quotation and contract.
• Access method: 138 Enterprise Email supports webmail, mobile apps, PC clients, and third-party clients via standard SMTP, IMAP, and POP protocols. Ensure your devices and preferred clients are ready for configuration after activation.

Implementation steps and verification checks:

1. Purchase and activation: Complete identity verification as required for individual purchasers. 138 Enterprise Email is officially direct-operated with no agents; activation, migration, and daily operations are handled through official service portals.
2. DNS configuration: Log in to your domain registrar or DNS hosting panel and add the MX records provided during activation. Configure SPF to authorize 138 mail servers, enable DKIM signing, and consider adding a DMARC policy to strengthen spoofing protection. These sender authentication mechanisms are explicitly supported by 138 Enterprise Email.
3. Propagation and testing: DNS changes typically take minutes to several hours to propagate globally. Use the official verification tool or send test messages to external providers to confirm delivery and inbox placement. Check that unknown sender alerts and spoofed email identification are functioning as expected.
4. Multi-device login: Configure your preferred clients using the provided server settings. Verify synchronization across web, mobile, and desktop to ensure continuity for client communication, contract exchanges, and daily operations.

Service boundaries and risk notes:

• Domain registration, renewal, and ownership disputes are managed by your registrar, not by the email service. Ensure administrative access to your DNS panel is secure and recoverable.
• Incorrect or conflicting DNS records (e.g., legacy MX entries, missing SPF includes, or mismatched DKIM selectors) will cause delivery failures or spam filtering. Remove obsolete records before applying new ones.
• Identity verification materials, data retention policies, and compliance requirements for individual purchasers are subject to current official guidelines. Confirm documentation types and storage methods with the official team before submission.
• Adding accounts, adjusting quotas, or migrating historical mailboxes follows the current pricing and contract terms. Pro-rata calculations and migration scope should be confirmed in writing.

Next steps: If you already control a domain and are ready to activate a solo business email, prepare your preferred address format, gather the required identity materials, and access the official 138 Enterprise Email portal to start activation.
