Campaigns
Suppression lists that apply everywhere

Any list can now be marked as a suppression list, and everyone on it is blocked at send time — across campaigns, journeys, and signals. Yada also holds promotional outreach on its own when a guest has already rebooked.
Flag a list as suppression once, and it applies to every product automatically
Campaign audience counts and send eligibility reflect suppression before you launch
Guests with an upcoming stay are skipped for win-back messages, even if they booked after enrolling
A deliberate per-campaign override is there for the times you genuinely need to reach a suppressed audience
