Iterable allows you to cancel and reschedule scheduled campaigns or abort active blast campaigns.
First, locate a campaign you'd like to cancel, reschedule or abort by navigating to the main campaign page and clicking on the campaign name in the All Campaigns tab.
To cancel a scheduled campaign from the Review & Launch page, just click on the Cancel Campaign button underneath the Campaign Details. You will then be asked to confirm if you want to cancel the campaign. If you click Yes, the campaign will be canceled. After you cancel a scheduled campaign, you can edit it and send it immediately or reschedule it for a later time.
To reschedule a scheduled campaign from the Review & Launch page, just click on the Reschedule Campaign button underneath the Campaign Details.
You will then be able to provide details for when you would like to reschedule your campaign. You can select a send time up to seven days in the future. You also have options to make it a recurring blast campaign and to send it based on the project's timezone or the recipient's timezone. You can learn more about timezone based sends here.
To abort a campaign, navigate to the Campaign Analytics page and click on the Abort Campaign button underneath the campaign details. Aborting a campaign will prevent any unsent messages from being delivered and stop any active experiments.
