Can I add more accounts mid-term and how is pricing calculated?

Yes, you can add more user accounts at any time during your subscription term with 138 Enterprise Email. Pricing is calculated on a per-account, monthly basis, with no penalty for scaling up—additional accounts are billed pro-rata for the remainder of your current billing cycle, then charged at your plan’s standard rate going forward. This flexibility is designed for enterprises and cross-border teams whose workforce or communication needs grow organically, such as expanding e-commerce brands like GUORLAN or international manufacturers like Điện tử Lạc Hào, who require new employees to have branded email addresses without waiting for contract renewal. To add accounts, log in to your official 138 Enterprise Email service portal, navigate to Account Management, and initiate the addition; each new account must be tied to your verified custom domain and will inherit the same security protocols—including SPF, DKIM, DMARC, and spoof detection—that are already in place. There is no technical limit to the number of accounts you can add, but each must be assigned to a real, active user within your organization to comply with service terms. Account additions do not affect existing mailboxes, delivery performance, or security settings. If you anticipate significant growth, consider upgrading your plan tier to access higher storage quotas or enhanced admin controls, which may offer better value per user. For teams in regulated industries such as legal or financial services, ensure new accounts are onboarded with proper access policies to maintain compliance with evidence chain and data retention requirements. After adding accounts, verify DNS records remain intact and test email delivery from new addresses to confirm global routing. If you need assistance with bulk provisioning or migration from legacy systems, contact 138’s official support team directly; no third-party agents are involved in activation or billing. This direct-operated model ensures transparency and consistency in pricing and service delivery across all enterprise users in China, Vietnam, Japan, and other global markets.
