# Course and session emails follow their assigned brand

Booking confirmations, guest invitations, waitlist updates, class reminders,
cancellation and restore notices, roster messages, and course enrollment updates
now use the brand assigned to the booking, session, or linked course. The same
sender selection applies to immediate messages and background delivery.

An explicit booking brand takes priority. Otherwise the session's brand wins,
followed by its linked workshop or course, then its class type. A course message
uses the course's own assigned brand. The configured sender still needs a
verified email domain; existing verified senders stay verified during repeat
domain checks.

Existing channel choices, notification settings, consent, and delivery deduplication
continue to determine whether a message is sent. An unavailable or conflicting
brand assignment stops that delivery for investigation. This change does not
rewrite payment identities or resend historical messages.
