High spenders in Klaviyo


Knowing which of your leads and prospects are most likely to spend big gives you the opportunity to serve them just the right offers at just the right time to drive revenue.

The most effective way to predict high-spend customers is with machine learning. With machine learning, you can constantly keep your lists of leads and prospects up-to-date with high-spend predictions based on the historical data of similar shoppers, and plug your high spenders right back into your stack, no PhD required. With your high spenders in your stack, you're ready to kick off a campaign to drive them to conversion.

Faraday makes predicting your high spenders intuitive & easy, and delivering them to any channel in your stack a breeze.

With high spend score predictions in Klaviyo, you'll give your team the ability to target not just those likely to become customers, but those most likely to spend big.

Follow the steps below to get your high spenders predictions into your Klaviyo account.

In this guide, we'll show you how to:

  • Organize your customer data into cohorts
  • Describe predictive models for high spenders with outcomes
  • Deploy high spenders predictions to Klaviyo using Pipelines

Getting started

Make sure you have a Faraday account (signup is free!) and that it's not in test mode.


You'll need the following cohorts available in your Faraday account:

Now you'll create the prediction objective(s) necessary to complete this use case with Faraday.


Outcomes use machine learning to predict whether or not people will exhibit a certain behavior.

Likelihood for high spend

Let's make an outcome for likelihood for high spend.

  • In the navigation sidebar, choose Outcomes. Screenshot of the outcomes list
  • Click the New outcome button.
  • Fill out the form:
    • For Eligibility cohort, pick the cohort that best represents your customers.
    • For Attainment cohort, pick the cohort that best represents your high spenders.
    • Leave Attrition cohort blank.
    • Skip over Trait blocking.
    • Enter a memorable name, like "Likelihood for high spend". Screenshot of the new outcome form, filled out
  • Click the Save outcome button.

Faraday will do some magic in the background, so you can proceed with the rest of the instructions. When your outcome is done building, you'll get an email, and you can review your outcome.


Now you'll configure the pipeline that deploys your predictions to klaviyo.

Create your pipeline

  • In the navigation sidebar, choose Pipelines. Screenshot of the pipelines list
  • Click the New Pipeline button.
  • Fill out the form:
    • For Payload, choose the following:
      • Outcome: Likelihood for high spend
    • For Population to include, choose the following:
      • A cohort representing your customers
    • For Population to exclude, choose the following:
      • A cohort representing your high spenders
    • Enter a memorable name, like "High spenders in Klaviyo". Screenshot of the new pipeline form, filled out
  • Click the Save pipeline button.

Your pipeline will start building in the background. You can proceed immediately with the next set of instructions.

Deploy your pipeline


  • In the Deployment area, find the CSV module and click Add. Screenshot of the ready pipeline with no targets yet
  • Fill out the popup:
    • Choose the Identified option.
    • Skip the advanced settings. Screenshot of the new target form, filled out
  • Click the Finish button.
  • Click the Test deployment button and confirm the results meet your expectations. Screenshot of a target after hitting its test button the first time Faraday will finish building your pipeline in the background. When it's done, you'll get an email—return to the pipeline and click the Enable pipeline button to activate it.


With your pipeline deployed, it's time to plug your high spend scores into Klaviyo. Follow the steps below to see each Klaviyo contact enriched with their high spend score.

Importing your high spend score CSV into Klaviyo

  1. In your Faraday pipeline, click the Download CSV button under the deployment to download your high spend scores as a CSV.
  2. Navigate to Klaviyo's Lists & Segments, and click create a list/segment in the upper right.
  3. Select list, as you'll need to create a list with these contacts and create the high spend score property during upload.
  4. Give your list a unique name and, optionally, a tag. Click create list.
  5. Select upload contacts.

klaviyo create list

  1. You'll be taken to the field mapping screen, where you can map any fields that didn't automatically map.

klaviyo import mapping

Under the "Klaviyo field" column, key rows to map to are email and the high spend score row outlined in step 7. Rows like "fdy_batch" and "dataset_id" can be skipped, as can the raw decimal score, which is generally the row before the score in step 7.

  1. In the final row, "fdy_outcome_propensity_percentile", click unmapped, and type in a unique name for this field, such as "high spend score." Then, click create option.

new klaviyo property

  1. In the final column for your new high spend score property, "type," change string to numeric, as scores will be numbers. This will enable you to create segments of contacts whose score is higher than a specific value.
  2. Click import review in the upper right to see the final report of columns being imported, properties being created, and columns skipped. Click start import to wrap up, and you can now begin to plan a campaign to target the high spenders in this list.

🔒 It's a best practice to permanently delete any file that contains personally identifiable information (PII) after use. Any deployment from Faraday that is unhashed contains PII, and should be deleted after uploading it to your destination for security purposes.
