How to Back-Populate a Flow

Last updated at:


Back-populating allows you to retroactively add qualified recipients into a flow. In this article, we explain how to back-populate. If you want more details on how back-populating works, read How Back-Populating Works in Klaviyo.

Callout: You cannot back-populate a flow that contains dynamic coupons. If you have any dynamic coupons, please change them to static coupons before back-populating.

How to Back-Populate a Flow

To back-populate a flow, click on the Flows tab, and then on the name of the flow. Check that the flow is in either manual or live mode before back-populating.

Click on the Manage Flow dropdown in the header and click Back-Populate Flow Recipients


Please note that if you are back-populating a flow with one or more SMS messages in it, you will want to review the message sending speeds associated with your account for a more accurate representation of when your text messages will actually go out.

Whether the flow is triggered by a list, segment, or metric affects your options for back-populating. List- and segment-triggered flows can back-populate either relative to when you hit back-populate, so all recipients start at the beginning of the flow, or relative to where the recipient falls within the flow's timeline, so recipients will join the flow based on when they joined the list or segment. Metric-triggered flows only back-populate relative to when someone performed the action that triggered the flow. 

There is no option for back-populating price drop- or date property-triggered flows. To learn more, check out How Date-Based Flows Queue Recipients.
