Contact Segment Automation Flow

Contact Segment triggered automation flows run when a contact enters or exits a defined segment. Segment entry and exit-based automation is a flexible and effective way to create targeted, personalized automation flows for your audience.

By using segments in your flows, you can reach contacts who are newly added, re-added, or have recently dropped out of a segment. This helps you deliver relevant content and timely offers based on user behavior or status, improving engagement and retention.

Here are a few ways you can use the Contact Segment Trigger automation type:

  • Welcome new sign-ups – Automatically send a welcome email, SMS, or WhatsApp message when a contact enters a designated segment.

  • Drive re-engagement – Send targeted follow-up messages to contacts re-added to a segment after inactivity or disengagement.

  • Target drop-offs – Trigger a message or offer when a contact exits a segment, such as unsubscribing from a product list or missing an activity.

  • Promote lifecycle campaigns – Initiate automation flows based on changes in customer segments, such as moving from “Leads” to “Active Customers.”

Before You Begin

  • Make sure you have at least one contact segment created. You’ll need it to configure the trigger. For more details, see the segments documentation.


Create a Contact Segment Automation Flow

Use the steps below to create an automation flow triggered when a contact enters or exits a specific segment.

Step 1: Open the Create Flow Panel

  1. Navigate to Automations > Flows.

  2. Click the + Create Flow button.

Open the Create Flow Panel.

Fig. 1. Open the Create Flow Panel.

Step 2: Select the Contact Segment Trigger

  1. Enter a descriptive name for your automation flow (for example, Engaged Users).

  2. In the Select a Trigger window, click Contact Segment.

  3. Click OK to confirm.

Select the Contact Segment Trigger.

Fig. 2. Select the Contact Segment Trigger.

Step 3: Edit the Contact Segment Trigger

To proceed with the automation setup, the Contact Segment Trigger must be configured. This is a required step before the flow can be activated.

You can edit the Contact Segment Trigger using one of the following methods:

A. Click the editsymbol icon on the trigger object in the automation flow builder.
B. Click the Edit trigger button.

Edit the Contact Segment Trigger.

Fig. 3. Edit the Contact Segment Trigger.

Step 4: Configure the Contact Segment Trigger

In the Edit Contact Segment Trigger panel, complete the following steps:

  1. Set the trigger condition – Use the dropdowns to choose when the automation flow should trigger (e.g., when a contact enters or leaves a segment named Signed Up).

  2. Select the segment – Choose the target contact segment from the list.

  3. (Optional) Add filters – Refine which contacts activate the automation flow based on additional conditions:

    • Use All of (AND) or At least one (OR) logic to group multiple conditions.

    • Click + Add Condition / Group.

    • Select a filter, such as Contact Attribute: SMS Subscribed = True.

  4. Click Save to apply the trigger settings and return to the automation flow builder.

Step 5: Build the Automation Flow

After configuring the Contact Segment trigger, proceed to build the automation flow using available Actions and Rules in the drag-and-drop interface.

To build your automation flow, you will use two types of components:

  • Actions – What should happen (e.g., send a message, update a contact).

  • Rules – Logic-based controls that determine how and when actions are executed (e.g., wait, branch, check conditions).

Start by adding an action. For example, to send a welcome SMS:

  1. From the Actions panel, select Send SMS.

  2. Drag the Send SMS object to the + rectangle in the automation flow canvas.

  3. Once placed, a configuration window will appear where you can customize the SMS content and sender details.

You can repeat this process with other messaging channels or logic-based rules to create a fully automated flow tailored to your use case.

Once you understand the drag-and-drop process, review the available Actions and Rules described in the following sections to configure your automation flow in detail.


Actions in Flow Builder

Actions define what happens when a flow is triggered. These actions allow you to send messages, update contact information, manage lists, or interact with external systems.

Rules in Flow Builder

Rules define the logic that controls how and when actions are executed within an automation flow. They are used to introduce delays, evaluate conditions, and create decision branches based on contact data or behavior.

The table below describes the available rules, including what each rule does, the configuration inputs required, and examples of when to use them.

Rule

Description

Inputs Required

Usage Examples

time_delay Time Delay

Pauses the flow for a specified duration before executing
the next step.

Commonly used to introduce delays between automated actions,
ensuring proper message timing.

  • Delay – Duration to pause the flow

  • Time Unit – Seconds, minutes, hours, or days

  • Schedule a follow-up message (e.g., email or SMS)

  • Create wait periods between steps

  • Ensure sequential timing of actions

true_false True/False Branch

For detailed configuration steps and advanced usage, see the full documentation:

Step 6: Activate the Automation Flow

Once you’ve configured the main trigger object and built the flow based on your use case, you’re ready to activate the automation.

Note

  • The Activate button will be disabled if the trigger object (shown at the top of the flow) has not been configured. To complete this setup, click Edit Trigger or refer to Step 3.

  • After activation, you can pause the automation at any time if you need to make changes or temporarily stop the flow.

Follow these steps to activate the flow:

  1. Click Activate in the top-right corner of the automation flow builder.

Activate Button in the Flow Builder.

Fig. 6. Activate Button in the Flow Builder.

  1. A modal window appears with optional settings you can configure before activating the flow:

Activate Flow Confirmation Window.

Fig. 7. Activate Flow Confirmation Window.

In the Activate Flow window, you can configure optional settings to control how contacts enter, exit, or restart the automation:

Option

Description

Allow contact re-entry after exit

Allows contacts to re-enter the automation if they meet the trigger conditions again after exiting.

Set up wait time (only visible if re-entry is enabled)

Specifies how long the system should wait before checking if the contact matches the trigger conditions again.

Exit conditions

Defines when a contact should immediately exit the flow. For example, when they leave the target segment.

Restart conditions

Forces a contact to restart the flow from the beginning, regardless of their current progress.

Note

To configure Exit Conditions and Restart Conditions, click the Settings button inside the modal. These settings are optional and depend on your flow logic.

Tip

Adding the exit condition “contact exits the segment” is recommended when you want to stop contacts from continuing through the flow if they no longer belong to the segment. This helps ensure the automation behaves as intended.

  1. Once you’ve reviewed or configured the optional settings, click Activate to launch the automation.

    The flow status will change from draft to active and will automatically run based on the defined segment entry and exit conditions.
