How to cancel a scheduled or sending campaign
You will learn
Learn how to cancel a campaign that has been scheduled or partially sent. Campaigns that have already been fully sent cannot be cancelled. If you don't see the option to cancel a scheduled or sending campaign, check that your user role has permission to manage campaigns.
Learn how to make edits to a scheduled campaign.
For a campaign with multiple messages, cancel each message separately. Cancellation cannot be undone.
Cancel a scheduled campaign
- Click on the Campaigns tab.
- Expand the campaign if needed to show its messages, then click the 3-dot icon to the right of the message you'd like to cancel.
- Click Cancel.

- Click Cancel campaign in the confirmation dialog.
After confirming the cancellation, the message's status in the list changes from Scheduled to Canceled. You will also see a message that indicates to resend, you will need to clone the cancelled campaign.
For large campaigns, the scheduling process itself may take some time. On the scheduled campaign page, the Cancel send button is available while scheduling is in progress and after it completes.
Cancel a campaign mid-send
When you cancel a campaign mid-send, Klaviyo cannot unsend messages that have already been sent. Cancelling stops messages that are still waiting to be processed, but messages already being processed may still send.
- Click on the Campaigns tab.
- Expand the campaign if needed to show its messages, then click the 3-dot icon to the right of the message you'd like to cancel.
- Click Cancel.
- Click Cancel campaign in the confirmation dialog.
After confirming the cancellation, the message's status in the list changes from Sending to Canceled.
The number of messages from your campaign that ultimately get delivered depends on when you click cancel and how far along the sending process is.
Available statistics for a partially sent message are in its overview report. The report shows the scheduled send date, but does not show a separate cancellation date.
