# Cancel A Newsletter Dispatch

Cancels a scheduled or ongoing email newsletter dispatch while canBeCancelled is true, returning it to draft and stopping further sends. Already sent mail cannot be recalled. Content and audience stay; prepare-newsletter-dispatch activates it again. Requires the user’s approval before stopping a deliberate dispatch.
