MailWizz is a self-hosted email marketing application requiring a valid purchase license. Unlike SaaS products, the license key must be manually installed on the server’s file system. Without a valid license, MailWizz will redirect to the purchase page or display a "License Invalid" error, halting all marketing operations.
