## Kaltura Messaging API

The Messaging API enables sending personalized, template-based email communications to Kaltura users — event invitations, attendance confirmations, reminders, and follow-ups. Templates support dynamic tokens (user profile fields, magic login links, QR codes, unsubscribe links) that are resolved per-recipient at send time. Built-in delivery tracking, engagement analytics, and CAN-SPAM compliant unsubscribe management complete the lifecycle.
