Is there any unique identifier or attribute, we can use for both static and dynamic marketing list members?
Hello,
you can easily extend the Contact entity or use the crmobjectID on contacts to identify members on the marketing lists. For static marketing lists there is also the concept of a "lists member" which has its own ID, yet this does not exist for dynamic marketing lists.
For Static and Dynamic Marketing lists (of the classic basic lists and campaign management domain in Dynamics 365 ) APIs are available to access list members or run the dynamic lists query even from external consumers.
Not sure whether this answers your question.
