   Some customers are experiencing delays with campaigns sending, and some scheduled campaigns may appear stuck or show no recipients while they process. We have identified the issue affecting a subset of campaign sending. If a scheduled campaign has not started sending, you can cancel and reschedule it to send again. We are working to resolve this as quickly as possible and will share another update shortly.
