Segments vs Lists
Segments are able to leverage conditions, behaviors, and fields within Paminga to pull together a group of Contacts. Segments are dynamic and perpetual, meaning that they will continue to add and remove Contacts from the Segment based on the conditions set. Segments can leverage Lists as part of their conditions.
Lists are static. Contacts on the list will remain on the List until an outside action removes them from the List (such as a Campaign action).
Both Lists and Segments can be used in the Participants Tab of a Campaign.
