How do I set up a journey that continuously adds users from a segment?

With an Audience-based entry there are two ways to keep adding users after the journey is live. Which one you need depends on whether you want a continuous trickle or a repeating batch.

Option 1 — let new segment matches in continuously

In the Audience-based entry element, under Define who enters the journey, choose:

• Existing users only (default) — only users who match the segment at launch enter. Nobody enters afterwards.
• Existing + new users — matching users enter at launch, and anyone who becomes a match later enters as well.
• New users only — nobody enters at launch; only users who start matching after activation enter.

Segment limitations: Existing + new users and New users only do not support event-based segments. Segments created by CSV import are static — new users are never added to them, so use Existing users only. RFM segments only pick up new users after you recalculate them in Audience > RFM Segmentation.

Option 2 — re-run the entry on a schedule

Set Entry schedule to Recurring entry and pick:

• Periodically — set the interval under ENTRY EVERY (e.g. every 1 day, every 2 weeks), then the days, time and timezone.
• On specific dates — pick dates in the calendar and click + Add Date for more.

The segment is recalculated before every scheduled entry, so users who joined it since the last run are included. Users already inside the journey at that moment do not enter again. If a subscriber's scheduled time has already passed, they are picked up on the next scheduled run.

How different entry types compare

• Audience-based entry: use the settings above to add users over time.
• Trigger-based entry (formerly "event-based"): needs no schedule — a user enters as soon as they fire the specified event.

Re-entering a journey

A user can re-enter a journey after completing and exiting it, through any entry point they qualify for, unless a Campaign entry limit is set (Settings > Campaign entry limit: once in a lifetime, once a day, once a week, once in three months, etc.). A user cannot be active in the same journey more than once at the same time.
