COMMERCIAL TERMS
Paid Zimphony licensing separates perpetual usage rights from ongoing update and support entitlement.
One commercial license covers one licensed Zimphony deployment—not each mailbox or domain.
Your right to use the licensed software does not expire.
12 months included with new paid licenses. Optional annual renewal at 25% of the then-current licensed edition and capacity price. If not renewed, the perpetual license continues to operate; eligible updates and covered support end. Reinstatement is available within three years of expiry.
Your Zimphony license remains valid when you upgrade the underlying Zimbra server. A new Zimphony license is not required. Compatibility remains subject to the Zimbra versions supported by the applicable Zimphony release.
Eligible same-deployment paid-license upgrades receive 100% License Upgrade Credit. Pay only the difference.
ELIGIBLE SAME-DEPLOYMENT UPGRADE EXAMPLE
For an eligible paid-license upgrade on the same Zimphony deployment, the full paid value of the current license is credited toward the higher license. Upgrade anytime. Pay only the difference.
MORE SAME-DEPLOYMENT EXAMPLES
The credit applies to eligible paid-license upgrades on the same licensed deployment. It is non-cash, non-refundable, non-transferable, and cannot be combined across licenses or deployments. It excludes Support & Update fees. Upgrading does not reset the existing Support & Update expiration date. No downgrade refund applies.
Licensing follows the Zimphony deployment—not individual mailboxes or domains. A server, VM, or legitimate hostname change does not itself require another purchase. Multiple Zimbra mailbox servers require a Zimphony deployment and applicable commercial license alongside each mailbox server.
Review deployment architecturePRICING FAQ
Commercial terms, deployment implications, and product boundaries in plain language.
Yes. Webmail Free is permanently free and production-usable. It has no expiry, registration requirement, or license key. It includes Zimbra Mail and Zimbra Contacts, with unlimited Active Mailboxes and domains from the Zimphony side.*
New paid licenses include 12 months of Support & Update. Annual renewal is optional and is priced at 25% of the then-current price of the licensed edition and capacity.
No. Annual Support & Update renewal is optional and separate from perpetual usage rights.
Native Zimbra and Google Connect use the same public capacity choices: 50, 100, 250, 500, and 750 Active Mailboxes. Deployments with 1,000+ Active Mailboxes are handled through Contact Sales.
The existing licensed software continues to operate. Active Support & Update is required for eligible Zimphony software updates and covered support. Renewal is optional and does not determine whether the perpetual license remains usable.
Annual Support & Update renewal is optional and is priced at 25% of the then-current price of the licensed edition and capacity.
Support & Update may be reinstated within three years of expiry by paying outstanding annual renewal fees, calculated at 25% per missed annual renewal using the then-current price of the licensed edition and capacity at the time of reinstatement, capped at the then-current price of a new license.
If Support & Update has been expired for four years or more, a new license must be purchased at the then-current price.
Renewal, reinstatement, or purchasing a new license does not require reinstallation or mail-data migration.
No. The standard license does not include the original development source code. The Python backend is compiled using Nuitka, while the frontend is delivered as production build files. As with browser-delivered software, frontend JavaScript and CSS may be technically inspectable, but these files are not the original development source code. Use, modification, reverse engineering, and redistribution remain subject to the license terms and applicable law. Original source code or additional source-code rights may be available under a separate commercial agreement; contact Sales to discuss your requirements.
No. Upgrading the underlying Zimbra server does not itself require a new Zimphony license. Technical compatibility remains subject to the Zimbra versions supported by the applicable Zimphony release.
