How do I set up auto reply and email signature on my solo business email?

You can configure both auto-replies and custom email signatures directly through the 138 Enterprise Email web portal or official management console, and they will synchronize to your mobile app, PC client, and supported third-party mail applications. To begin, log in with your custom domain credentials, navigate to Account Settings, and use the built-in editors to draft your out-of-office message and branded signature template. Ensure your third-party clients are correctly mapped to the provided IMAP/SMTP servers with SSL/TLS enabled; if your account uses enhanced security policies, generate a dedicated client password during setup. Please note that auto-replies are intended for scheduling convenience and do not replace manual verification for high-risk requests like payment changes. Signatures should avoid unverified claims to maintain compliance. For detailed step-by-step procedures, refer to the enterprise email operation guide, or contact the officially direct-operated support team through the service portal if you need assistance with multi-device sync or domain authentication.
