What is the exact annual cost for a single-user enterprise email with custom domain?

The exact annual cost for a single-user enterprise email with a custom domain is not publicly listed on our website and may vary based on specific service configurations, security features, and regional factors. Typically, pricing depends on factors such as storage capacity, advanced security options like anti-spam and anti-virus, global delivery nodes, and official direct-operated support for activation and migration. For accurate pricing, enterprises should contact our sales team with details about their domain, security requirements, and intended use cases (e.g., cross-border communication or compliance needs). Note that costs may include additional fees for migration services or premium features. Next, we recommend preparing your domain details and security preferences, then reach out via our official service portal for a customized quote.
