How do session limits and segment entry rules work in a customer journey?

Session limits and entry rules control when and how often a user joins a journey. These rules operate on several levels.

Journey limits

Settings for session counts and entry rules apply only to the specific journey where you set them. They do not change how other campaigns in your project behave. By default, a user cannot have two active sessions in the same journey at the same time. They must finish their current path before they can enter again. The only exception is if you use unique identifiers like an order ID to allow multiple separate sessions.

Global limits and segment settings

The global entry limit and the segment block settings work at the same time. The global limit is a hard rule that starts a countdown from the exact moment a user joins the journey. For example, if you set a one-week limit, the user cannot start that journey again for seven days.

Re-entry and resuming

If you choose to stop users from re-entering a segment when a campaign resumes, they will not start the journey over. If they are already in the journey, they stay at their current step and continue from there. For a user to start a journey from the beginning, both the segment trigger and the global entry limit must allow it. If either setting blocks the user, they will not enter.
