How to Resend a Campaign to People Skipped by a List-Triggered Flow

Last updated at:


The main reason you would want to send a campaign to a group of people who were skipped by a list-triggered flow (for example, a welcome series) is if you have an existing flow, but a number of people were skipped by a flow email for some reason. Perhaps you initially had the wrong filters on the flow, or Smart Sending was on by mistake.

This guide will walk through how to build a segment of people who should have received a list-triggered flow and send them a campaign. This approach works best when you have to resend to a large group of people or if you need to resend an SMS message; if you instead only need to send to a few people, check out our guide on resending emails in Klaviyo.

If you would like to email people who qualified for the flow's conditions before you created the flow, you should instead back-populate the flow

Build a Segment of Contacts Skipped by a Flow

First, build a segment with conditions that exactly match the trigger and event filters of the flow. Then, add an AND condition stipulating that they have never received the flow email or SMS that they were skipped from.

In the example below, we are trying to identify people who were skipped from receiving a welcome series email that was meant to only send to customers who have never purchased before five days after they sign up.


In this example, our flow is triggered by being added to our "Newsletter" list, and there is a five-day time delay between when they sign up and when they should receive the specific email. Because we don't want to identify people who were skipped by the entire flow — just one specific email — we can identify this email by the subject line rather than the name of the flow. For SMS messages, you can instead use the Received SMS metric. 

Save the Flow Message as a Template (Email Only)

Save a flow message as a template by first navigating to the Flows tab and selecting the appropriate flow. Then, click the email and choose Edit from the left-hand panel. Lastly, save the template by clicking the dropdown arrow beside the Edit Content button (not the button itself). Next, name and save your template.


Create a Campaign

Navigate to your Campaigns tab and create a new campaign. When configuring the campaign, select the segment of people who were skipped by the flow message. Make sure that Smart Sending is turned off.

For emails, select Use Template and find the template you just saved. 


As for SMS, you can copy the content from the flow message and paste it into the campaign. 

Then, you can schedule the message to send immediately or at a later time.
