Segment customers using Boulevard data

Segment customers using Boulevard data

You can use Boulevard’s metrics to segment customers and target them with a campaign. For example, you can create a segment of everyone who has completed an appointment in the last 30 days and send a campaign to that segment.

Example segment which checks if someone has Completed Appointments in the last 30 days.

To create the example segment shown above:

  1. Click the Audience dropdown in the left-hand navigation sidebar.
  2. Click Lists & Segments.
  3. Click Create List / Segment in the top right.
  4. Select Segment.
  5. Name your segment and select tags if desired.
  6. Under Definition, select What someone has done (or not done) > Completed Appointments > at least once > in the last > 30 > days. If you have multiple integrations, make sure to choose the Completed Appointments metric with the Boulevard logo.
  7. Click Create Segment.

For this example, if you’d like to make sure the segment only includes people who completed an appointment for the first time:

  1. Click AND to add a new exclusive condition.
  2. Add the condition What someone has done (or not done) > Completed Appointments > equals > 1 > over all time. This will exclude anyone who has completed an appointment more than once.

Example segment which checks if someone has only Completed Appointments once over all time.

Use Boulevard data in flows

Use Boulevard data in flows

You can use Boulevard metrics to trigger flows. For example, use the Completed Appointments metric to trigger a flow to send messages to someone immediately when they complete an appointment.

If you are using Boulevard to send email and SMS notifications, make sure to turn off messages that you would rather send through Klaviyo flows so that your customers aren’t receiving repetitive messages. See Boulevard’s support documentation for more information on how to disable email and SMS notifications.

To create a flow using Boulevard metrics:

  1. Navigate to the Flows tab from the left-hand navigation sidebar.
  2. Click Create flow in the top right.
  3. Click Create from scratch in the top right.
  4. Name your flow and select tags if desired.
  5. Click Create Flow.
  6. In the flow builder, choose Metric as the trigger.
  7. From the dropdown, select a Boulevard metric, such as Completed Appointments, indicated by the Boulevard icon.
    Choosing the Completed Appointments metric as the trigger in the left sidebar of the flow builder.
  8. Click Done.
  9. Add a message relevant to the triggering action, such as a thank you message.
