Open the queue of outgoing campaigns (Delivery > Queue).

There are three tabs:

• The Queue with the campaigns waiting in line
• In Delivery with all campaigns which are currently sent out
• Network with all network campaigns (special feature)

Campaigns in the queue can be stopped by clicking cancel delivery up to 5 minutes before start of delivery. They are then removed from the queue and put back to Drafts. The target group will receive the prefix “CANCEL_” and will be moved back to the address lists.

Directly after the stop you will receive the message “???” (hierzu muss ich erst eine Kampagne abbrechen, um die Meldung zu sehen). In the queue this will be notified by the message SEND_QUEUE_CAMPAIGN_CANCEL_IN_PROGRESS. After a short while the campaign is not visible in the queue anymore but will be seen in the drafts. The cancelation will be listed in the campaign’s logfile. [2019-07-04 17:04] delivery cancelled by xy / promio.net GmbH

Also running deliveries (type: default) can be canceled or paused. This does not count for A/B tests, automatic, transaction or network campaigns.
