You can continue to upload guests into the platform via an eClub upload and you may wonder if these uploads will dynamically update existing eClub guests segments.
The eClub guests segments do not dynamically update, any new eClub uploads will have to be added to the segment via the Segment Attributes - Bulk Guest Uploads Section. When the new eClub upload is added to the Segment Attributes of an eClub guests segment, the guests in the upload sheet will be added to the Segment.
