in Reactions, you may select when you want the reaction to happen, during a user’s journey through a segment.
- On Entry - triggers the reaction only when the user lands on a page and enters the segment criteria
- On Exit - triggers the reaction only when the user lands on a page and leaves the segment criteria
- Every Time - triggers the reaction every time the user lands on a page and meets the segment criteria
More information on triggering logic can be found here.
