Prevent a Workflow from Running on the Same Contact Twice

03/09/2026

Exit Steps in workflows now do more than end the current run. You can now use an Exit Step to prevent the same workflow from running on the same contact again in the future.

What’s New

Exit Steps can now permanently block future runs — Once a contact reaches an Exit Step, that workflow will not run for that contact again.
This applies across workflow versions — Even if you publish a new version, contacts who already exited through an Exit Step will still stay blocked from future runs.

How It Works

A contact can enter a workflow through a trigger like Contact Created, Contact Updated, Manual Trigger, Appointment Created, or Form Submission Created. If that contact later reaches an Exit Step, the workflow run is completed and that contact is permanently excluded from that workflow.

A contact enters the workflow through a trigger.
The contact moves through the workflow steps.
When the contact reaches an Exit Step, that workflow run ends.
If the same workflow trigger happens again later for that same contact, the workflow will not run again.

Example: A workflow uses the Contact Updated trigger and watches the Tags field.

A contact gets the tag Seminar Attendee, so the workflow runs.
Later, the same contact gets another tag, such as Hot Lead.
Previously: The workflow could run again because the contact still matched the original tag condition.
Now: If that workflow path ends with an Exit Step, the workflow will not run again for that contact.

What This Means for Existing Workflows

Workflows without an Exit Step: No change. These workflows continue working the same way as before.
Workflows with an Exit Step: Going forward, any contact that reaches the Exit Step will be blocked from running through that workflow again.
Contacts who already reached an Exit Step before this update: They are not blocked retroactively. They can still enter the workflow again unless they reach the Exit Step in a new run after this update.
Runs that were terminated or failed: These do not create a permanent block.
Workflows that end naturally without an Exit Step: These do not create a permanent block, so the contact can still enter again later.

What About Contacts Already in Progress?

Contacts already in the middle of a workflow are not affected immediately. Their current run continues normally.
If their current workflow path includes an Exit Step ahead: They will be blocked from future runs only when they eventually reach that Exit Step.
If their current workflow does not include an Exit Step: No permanent block will be created.
If you publish a new version of the workflow: Contacts already in progress continue on the version they started on.

When to Use an Exit Step

Use an Exit Step if you want the workflow to run only once per contact.
Let the workflow end naturally if you want the workflow to remain repeatable in the future.

Why It Matters

Better control for one-time workflows — Prevent onboarding, one-time follow-up, or single-send workflows from running more than once for the same contact.
Fewer duplicate sends — Reduce the risk of a contact triggering the same workflow again later.
More predictable workflow behavior — Exit Steps now clearly define when a workflow should end permanently for a contact.
