Frequently Asked Questions

Are there truly zero recurring monthly or annual costs?

Yes. You purchase the physical hardware outright. The embedded email server software, administrative panel, unlimited mailbox accounts, and unlimited domain bindings belong to you perpetually.

What happens if our company grows from 20 to 100 people?

You do not pay a single cent more. Simply log into the local admin dashboard and create new accounts. If you need more storage in 3 years, plug in a standard SSD drive.

How do we pay via bank wire or company PO?

Click "Request Proforma Invoice (Wire Transfer)" above. You will immediately receive an official Proforma Invoice under HONGKONG HUIHUANG INDUSTRIAL CO., LIMITED containing international SWIFT and US ACH remittance details.

What is the 30-day money-back guarantee?

Test XMAILBOX in your network for 30 days. If it doesn't meet your organization's email and privacy requirements, return the unit for a full refund of your purchase price.
