Segment Users by Subscription Preferences

It is possible to segment based on users' subscription status to the different categories. To do so, either from the segmentation on a campaign level (from the Segment tab) or directly from the segmentation engine (Data > Audiences > Segments > Create a segment), select the condition Engagement > Subscription Prefs. Select the desired category. It will be possible to segment based on who is subscribed or not subscribed to that specific category.

You can also include consent preferences when exporting the segment.

Navigate to Audiences → Segments.Select a segment, click on the three dots menu, and choose Export Users → Users.
In the Customize Export popup, you’ll find an Export Preferences section. Use this to add the consent preferences relevant to your needs.
