The Complete Guide to MailWizz License Key Management 1. What is the MailWizz License Key? The MailWizz license key is a unique alphanumeric string (e.g., MW-XXXX-XXXX-XXXX-XXXX ) that validates your entitlement to use MailWizz Email Marketing Application (self-hosted version). Unlike SaaS products, MailWizz is a one-time purchase per domain, but the license key still enforces domain restrictions and enables updates. Key Characteristics:
One license = One production domain (+ optional subdomains) No recurring fees (lifetime updates for the same major version) Localhost / development environments are allowed without consuming a license The key does not expire – but can be blacklisted if abused
2. How the License Key Works (Technical Flow) When you install or run MailWizz, the system performs periodic validation calls to the MailWizz license server ( https://www.mailwizz.com ). Validation Process: 1. MailWizz sends a POST request to: https://www.mailwizz.com/api/license/validate
Request payload includes:
license_key (your key) domain_name (where MailWizz is installed) ip_address (server IP) app_version (current MailWizz version)
MailWizz license server responds with:
status (valid / invalid / blocked) latest_version (if valid) error_message (if invalid) mailwizz license key work
MailWizz caches the result (default: 24 hours) in database.
