Can I add more users to a solo business email plan with 138 Enterprise Email?

Yes. If you initially purchased a single-account 138 Enterprise Email plan for your solo business, you can add more user accounts later as your team or workload grows. 138 Enterprise Email supports account expansion during the active service period, and the specific cost adjustment and pro-rated billing will follow the current quotation and your service agreement.

Who This Applies To

This option is designed for individual operators, freelancers, foreign trade SOHO professionals, independent consultants, small studios, and early-stage startup teams who started with a one-person custom domain email setup and now need to onboard staff, create departmental addresses (such as sales@, support@, or billing@), or separate personal and business correspondence under the same branded domain.

Preparation Before Adding Users

• Domain control: Ensure the custom domain bound to your 138 Enterprise Email is still under your management and that DNS records (MX, SPF, DKIM, DMARC) remain correctly configured.
• Account naming plan: Decide the new mailbox addresses and aliases in advance, for example, using employee names or functional roles.
• Client access readiness: Confirm which devices and clients the new users will use. 138 Enterprise Email supports webmail, mobile apps, PC clients, and third-party standard protocol clients via SMTP, IMAP, and POP.

Implementation Steps and Checkpoints

1. Log in to the admin console of your 138 Enterprise Email account using your administrator credentials.
2. Submit an expansion request through the official service portal or contact the officially direct-operated support team to add the required number of accounts. Since 138 Enterprise Email is officially direct-operated with no agents, all account additions and billing adjustments are handled through official channels.
3. Confirm the pro-rated fee for the additional accounts based on your remaining service term and the current pricing structure.
4. Create the new mailboxes in the admin panel once the expansion is approved and activated.
5. Configure security settings for each new user, including strong passwords, sender authentication alignment (SPF/DKIM/DMARC), and device login permissions.
6. Test sending and receiving from each new account across web, mobile, and desktop clients to verify global delivery and multi-device synchronization.

Service Boundaries and Limitations

• Account expansion is only available during an active subscription; expired or suspended plans must be renewed first.
• The exact fee calculation and any minimum purchase thresholds are subject to the current official quotation and your contract terms.
• Adding users does not change your domain or existing mailbox data; historical emails and configurations of the original account remain intact.
• All new accounts inherit the same anti-spam, anti-virus, and spoofed email identification protections as the primary account.

Next Steps

If you are ready to scale your solo business email into a small team setup, log in to your 138 Enterprise Email admin console or visit the official service portal to request an account expansion quote. For migration of existing emails from other providers into the newly added accounts, the officially direct-operated support team can assist with migration planning and configuration.
