No Rule (Hand Pick)

Use this segment type when you wish to apply no filters and rules for creating segments so as to handpick and group customers into a segment.

Scenario: The business has customers from mail chimp and various other third-party apps that are important too irrespective of their interactions and behavior with the business. Customers such as these are to be engaged with different sorts of campaigns and thus you import the list of these customers and name the segment as ‘Customers From Third-Party Apps’.
