Journeys
Turning off a journey now stops queued sends

Deactivating a journey now stops the people already moving through it, not just future enrollments. In-flight executions are cancelled when the workflow is turned off, giving the switch the immediate behavior teams expect.
New contacts can no longer enter a deactivated journey
Existing in-flight enrollments are cancelled at deactivation
Queued steps check cancellation state before a message is sent
Teams can stop an automation without waiting for its current audience to finish
