Changing the audience
If you are working on a draft campaign, you can change the selected audience before confirming the submission at any time.
If it is a scheduled campaign, you can edit it from the Campaigns section:
Click on Edit and you will see the campaign editor, where you can reselect the audience by selecting a segment, data source, or tags.
You have to click on the box "Include Audience", and then you will be able to select your segments, data sources, etc.
