It is possible to add a filter to a view of contacts based on a related entity, "Segment". But this only allows selection of Outbound marketing segments. It appears there is no way to select in a similar way, based on Real Time Journey segments.

We have a business need to select a segment of our customer database and export the mail address data (postal mail - not email), and other fields, to provide data to a mailing house, to send out letters to our supporters.

The export from real time segments, only allows export of five columns, not including mail address information.

We need to use segments, because that is the only way we can select contacts by GIS tool (Maplytics in our case).

Selecting contacts in this way also opens up the ability to bulk edit contact data, without needin to export and reimport the data. Exporting and reimporting bulk contact data opens up a GDPR weakness, with data sets of personal data held outside of Dynamics
