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 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.
Here are some things to know before you begin this process.
Only Regular and Plain-Text 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 a campaign from a legacy Pay As You Go account, we'll return the unused credits after the cancellation is complete.
