 * Hello there, we’re planning to update the segment rules used in one of our workflows(
   trigger is “contact enters a segment”). Is there a way to set it up so that it
   doesn’t trigger again for contacts who were already in the workflow before the
   segment change?

 * Hi [@p1forferrari](https://wordpress.org/support/users/p1forferrari/),
 * That’s a great question — updating a segment that’s linked to an active workflow
   can definitely impact how that workflow behaves, so it’s good you’re checking
   before making changes. Here’s what you need to know:
 * **1. Impact of segment updates on workflow triggers**
    - **Changes in Segment:** Updating existing segment rules can cause customers
      to re-enter or exit the same segment. If the segment is tied to a workflow
      with a trigger such as **“contact enters/exits the segment,”** that contact
      may re-trigger the workflow.
    - **Risk of Duplicate Messages:** As a result, contacts who re-enter or exit
      a segment may receive messages they’ve already received in the past.
 * **2. Avoiding duplicate messages**
 * To prevent duplicate messages when editing segments:
 * Enable the **Frequency Setting** in the workflow associated with that segment.
   This ensures that a contact can trigger the workflow only once or within a specific
   timeframe.
 * **How to enable it:**
    1. Open the workflow associated with the segment.
    2. Click on the **Trigger block**.
    3. Scroll down to the **Frequency Setting** section.
    4. Enable the toggle and select one of the following options:
       – **Anytime in the
       Past:** Ensures the contact will not trigger the workflow again– **In the Last
       X Hours, Days, or Weeks:** Prevents re-triggering within your chosen time frame.
 * **3. Recommendations for editing segments**
    - **Review Associated Workflows:** Before making any changes, check which workflows
      are connected to the segment.
    - **Enable Frequency Settings:** Apply the Frequency Setting to workflows where
      you want to prevent re-triggering.

 * By reviewing and adjusting these settings before editing your segment, you’ll
   keep your automations running smoothly and avoid sending duplicate messages to
   the same contacts. If you’d like, we can help review your setup to make sure 
   everything’s configured as intended.
