Troubleshooting a flow

You will learn

Learn how to troubleshoot a flow when you notice it behaving differently from expected.

Understand flow alerts

Depending on the issue, you may see a red or yellow warning icon next to your flow in the Flows tab or on specific flow components in the flow builder. If you are not seeing any alert icons, skip to the next section.

For alerts on the Flows tab, hover over the icon to view a description of the issue.

For alerts in the flow builder, click on the Alerts in the bottom left of the builder to view a list of issues with flow components.

For more information, see our article on understanding flow alerts.

For new accounts

For new accounts, before you begin troubleshooting, please make sure you have fully read our guide on getting started with flows to understand the essential components of a flow and how to set your first flow live.

To avoid issues with common flow types such as welcome series and abandoned cart, we recommend creating your first flows using the pre-built templates from our flows library and editing the pre-built content to match your branding.

Review the flow’s changelog

If your flow was working previously, but you have recently noticed changes in behavior, you should first look at the flow’s changelog to view a history of changes made. This is especially important for older flows and accounts with multiple users. If you notice that a flow’s behavior has changed after a certain date and time, the changelog will be able to tell you the following:

• What changed
• Who made the change 
• When the change took place (date and time in your account’s timezone)

If a change coincides with when you started experiencing issues with your flow, it is likely that the change is the source of the issue. 

Follow these steps to view a flow’s history:

1. In the dropdown menu, click View Flow History.
   
2. Selecting View Flow History will open the Flow History panel on the right-hand side of the screen.
   

Find out more about the Flow History panel in our article on how to review the changelog for a flow.

Troubleshooting resources

Flow triggers

If the metric used to trigger your flow suddenly sees a drop in activity, you will receive an alert like the one shown below, and you must troubleshoot the issue to make sure the flow is triggering properly.

For Viewed Product, Added to Cart, Started Checkout, and Placed Order tracking, see the articles below for troubleshooting steps:

• Troubleshooting viewed product tracking
• Troubleshooting added to cart tracking
• Troubleshooting started checkout tracking
• Troubleshooting placed order tracking

For all other metrics, understand how Klaviyo monitors metric activity for flows.

Scheduled and skipped messages

If you are seeing a significant amount of skipped profiles in your flow, learn about troubleshooting why a flow message skipped a profile.

If you are seeing profiles scheduled in a flow multiple times, learn about troubleshooting why a profile is queued in a flow multiple times.

If you are unsure how or why profiles are moving through a flow, learn how contacts move through a flow.

Deliverability

If you are receiving notifications about sudden drops in flow performance, see how Klaviyo monitors metric activity for flows.

Troubleshooting specific flow types

If you are having issues with specific types of flows, see the articles below on further troubleshooting steps.

• Troubleshooting a list- or segment-triggered flow
• Troubleshooting a metric-triggered flow

If you aren’t sure which type of flow you are having trouble with, you can tell based on the flow’s trigger. 

1. Click on the trigger of the flow in the flow builder.
2. View the top section of the right sidebar to see if the flow is triggered by a list, segment, or a metric.
3. Determine what type of flow you are viewing:
• List- or segment-triggered flows are triggered when someone is added to a particular list or segment. Common examples include welcome series and VIP segment flows.
• Metric-triggered flows are triggered by metrics from your integrations such as your ecommerce platform. Common examples include abandoned cart and post-purchase flows.
