A target segment is just a set of rules, conditions, or criteria that you define to shortlist the guests who qualify the rules.
Important: Deleting a target segment does not have any impact on the past campaigns in which the target segment was used.
Before you begin, ensure you have the Delete permission for target segments (Admin > Security Roles > Marketing Manager > Permissions > Marketing Manager > TargetSegment > Delete).
On the main menu, click Marketing.
On the Marketing Dashboard menu to the left, click Segmentation > Target Segments.
Click the name of a segment you want to delete.
On the Edit Target Segment page, click Delete.
The target segment is deleted permanently.
