Stopping an Email Campaign After Sending Has Started
This guide explains how to stop an email campaign in Sender using the Email campaigns feature. It shows where to find running campaigns, how to halt the sending process, and what happens after you stop a campaign.
Where to Find This Feature
In the Sender dashboard, go to:
Email campaigns (left sidebar)
From the campaigns list, use the Filter dropdown to view campaigns by status: All, Draft, Scheduled, Sending, or Sent.
Steps to Stop a Campaign
Step 1 — Locate the Active Campaign
Navigate to Email campaigns from the left sidebar. Click the Filter button and select Sending to view only campaigns that are currently in the process of being delivered. The page displays a list of campaigns with their status, delivery statistics, and action buttons. Campaigns actively sending will show a SENDING status badge in orange.
Step 2 — Access the Stop Option
Find the campaign you want to stop in the list. In the Actions column on the right side of each campaign row, look for the stop icon (a circle with a line). This icon appears next to campaigns that are currently sending. Hover over the icon to confirm it displays Stop sending before clicking.
Step 3 — Confirm the Action
After clicking the stop icon, a confirmation dialog appears asking: "Are you sure you want to stop sending?" The dialog presents two options: No to cancel and return to the campaign list, or Yes, I am sure to proceed with stopping the campaign. Click Yes, I am sure to halt all remaining email deliveries immediately.
What Happens After You Stop
After stopping, the campaign remains in the Email campaigns list with a partially sent status. The campaign statistics will display the number of emails that were delivered before you stopped it, along with opened and clicks data for those delivered messages. You cannot resume sending to the remaining recipients from a stopped campaign. If you need to reach the remaining subscribers, you must create a new campaign targeting those who did not receive the original message.
Common Issues
Cannot find the stop option — The stop button only appears for campaigns currently in "Sending" status. If you're trying to cancel a scheduled campaign before it starts, use the "Cancel schedule" button instead.
Campaign already completed — If the campaign moved to "Sent" status before you could stop it, all emails have already been delivered and cannot be recalled.
Accidentally stopped a campaign — Stopped campaigns cannot be resumed. Create a duplicate campaign and resend to the subscribers who did not receive the original message.
FAQs
Can I stop a scheduled campaign before it starts sending?
Yes. For scheduled campaigns, click the cancel schedule icon (circle with line) in the Actions column. This returns the campaign to Draft status without sending any emails.
What happens to emails that were already sent?
Emails delivered before you stopped the campaign remain in recipients' inboxes. Stopping only prevents remaining emails from being sent.
Can I see who received the email before I stopped it?
Yes. The campaign statistics show delivered, opened, and clicked counts. You can view detailed recipient data in the campaign report.
Will stopping affect my sender reputation?
No. Stopping a campaign mid-send does not negatively impact your sender reputation. It simply halts the delivery queue.
