Journey Simulation allows marketers and customer experience teams to validate how profiles move through a Journey before launching it live. With Simulation Mode, you can instantly preview entry logic, branching behavior, wait steps, and message paths in a safe, controlled environment.
This helps teams test journeys confidently, reduce configuration errors, and launch campaigns with greater accuracy.
Use Simulation Mode when you need to:
Confirm that your entry criteria are correct
Preview how profiles will pass through decision points or A/B tests
Validate wait steps without real-time delays
Understand branching logic before publishing
Share and review journey behavior during QA
Troubleshoot unexpected logic before a journey goes live
Simulation Mode is designed for pre-launch validation and works best for journeys in the Draft state.
Below is where you will find the Simulation Mode entry point on the Journey Builder canvas.
Simulation Mode Button – Click this to begin validating and testing your journey.
Draft State Requirement – Simulation is only available when the journey is in Draft state.
Safe Testing Environment – No real profiles or activations are affected.
From any Draft journey, select Simulation Mode to begin validation instantly. The system automatically checks for missing or invalid configurations before entering the simulation environment.
Journey Simulation automatically selects profiles from the Parent Segment that meet the entry criteria at the time simulation begins. This provides a fast, frictionless way to test the journey.
Simulation Mode skips real wait times so you can immediately see how profiles progress through time-based steps. Each wait node displays simulated “entered” and “exited” timestamps.
Highlighted Paths – Shows which branches profiles actually followed.
Profile Counts – Each node displays how many profiles passed through it.
Simulated Wait Times – Displayed as “Entered” and “Exited” timestamps.
A detailed log panel summarizes key information, including:
Simulation start and end time
Parent Segment refresh time
Node-level entry and exit timestamps
Execution outcomes for each step
This helps teams validate logic and timing at a glance.
Open a journey in Draft state.
Click Simulation Mode.
Resolve any validation errors if prompted.
Allow the system to auto-select profiles or manually choose your own.
Click Run Simulation.
Review highlighted paths and the simulation log.
Rerun or exit simulation when finished.
Simulation Mode never modifies real profiles or live campaigns.
The following behaviors are expected in the current Early Access release:
Simulation is static: all profiles that satisfy the entry criteria enter the journey simultaneously.
Performance may vary based on journey size and system activity.
Jump steps are not supported in Milestone 1.
Profile attributes cannot be edited during simulation.
Simulated results are visible only while Simulation Mode is active.
Journey Simulation is currently available as an Early Access feature. Please contact your Customer Success Manager (CSM) to request enablement.
No. Simulation Mode does not affect any profiles, campaigns, or reporting.
No. Simulation Mode is available only for journeys in Draft state.
No. Simulation evaluates logic only. External systems are not triggered.
This indicates that no profiles visited those paths during the simulation.
Simulation time may vary depending on journey complexity and overall system activity.
