In order to further specify members for a defined segment, it would be essential to have available the following criteria:

"Email: Legal Destination".

By this one could separate commercial and transactional Markting Emails.

Use Case:

The goal is to have ALL contacts in a segments that are:

Status = active

Email delivered = more than 0 within the last 1 day

Email delivered = more than 8 within the last 28 days

AND Marketing Email “Legal destination” = commercial

By this one could e.g. specify the interval of Emailings, taking in account that only Commercial Marketing Emails are considered and the segment could be used to exclude the members of the segment in other running customer journeys.
