I need to maintain lists of project team members. All the possible members are present in CC as contacts. Their membership may change on a somewhat frequent basis.
If the members in a list change, I plan to delete all members from that list (REMOVE_CONTACTS_FROM_LISTS Activity) and then add the members to that list using a ADD_CONTACTS, SV_ADD activity.
Of course, I'll verify the remove is complete before doing the add.
The examples show supplying email, first name, last name for the ADD_CONTACTS, SV_ADD. Since I am certain the contacts already exist, do I need to supply anything more than a list of email addresses?
I need to do it this way rather edit the lists for each individual contact since there are only 275 lists but there are 3000+ contacts.
