Stops recipients you added, in every sequence at once. Cancelled recipients get no further emails, their open sequence tasks are deleted, and they are marked completed. Paused recipients are included; recipients that already finished are left alone.

Send emails to cancel only those people. Without emails, or with an empty array, every active recipient you added, in every sequence, is cancelled. To stop one sequence instead, use POST /v1/sequences/{id}/cancel.

To cancel for your whole workspace, send orgId with emails. If you are a workspace admin, the listed emails are cancelled in every sequence, whoever in the workspace added them. Other members cancel only the recipients they added.
