Cancel a Campaign

Mistakes happen, and sometimes the mistake is in a campaign we just sent. With Mailchimp's Stop Delivery feature, you can cancel a Regular or Plain-Text Email Campaign, or an SMS campaign, after you click Send and before all of your recipients have received it. After you cancel a campaign, we'll track which subscribers already received the campaign, so you can create a segment to exclude or resend to later.

This feature is included with the Premium plan.

Before you start

Here are some things to know before you begin this process.

  • Only Regular and Plain-Text Email Campaigns and SMS Campaigns can be canceled.
  • The campaign must have at least 10,000 recipients to be eligible for cancellation.
  • The cancellation option is only available while your campaign is sending. Smaller audiences process more quickly, while larger audiences take longer.
  • During the sending process, we'll show you the percentage of your subscribers who have received the campaign.
  • If you click to stop delivery, we'll start cancelling the campaign immediately. The process takes some time, though, so the final number of subscribers who receive the campaign may be higher than the percentage shown on the screen. When cancellation is complete, we'll send a confirmation email that lists the final number of recipients.
  • If you cancel an email campaign from a legacy Pay As You Go account, we'll return the unused credits after the cancellation is complete.

To cancel an email campaign with our Stop Delivery feature, follow these steps.

  1. Click Campaigns.
  2. In the Status column, click Cancel for the campaign you want to stop delivery.
  3. Click Cancel sending in the pop-up modal.

We'll email a notification to the Primary Account Contact when cancellation is complete and the final recipient list is available. This process could take up to several hours.

Cancel an SMS

You can cancel an SMS at any time while it’s still sending. This will cancel the remaining queued messages from sending.

To cancel an SMS, follow these steps.

  1. Click SMS.
  2. Scroll to the Recent messages section and find the SMS you want to cancel.
  3. Click the drop-down next to the View report button, then click Cancel sending.
  4. In the Are you sure you want to cancel? modal, click Cancel sending.

You can also cancel from the Campaigns page.
