How to Automate Your Warmy Seed List with Klaviyo and Make.com

Introduction

This guide explains how to set up an automation that syncs your Warmy seed list with Klaviyo using Make.com. You will generate API keys, retrieve your seed list split ID, prepare two Klaviyo lists, configure notifications in Warmy, and finish the setup using our public Make.com template ⭐

To get started, you first need to sign up for a Make.com account and purchase a subscription there 🙌

Step 1: Generate Your API Keys

To begin, create the required API keys:

  • In Warmy, generate a new API key.

  • In Klaviyo, generate a private API key.

Remember: Klaviyo shows this key only once, so copy and save it for later

Step 2: Find Your Seed List Split ID

To retrieve your split ID:

  1. Open the Warmy API documentation.

  2. Log in at the top right using the Warmy API key you generated.

Step 3: Create Two Klaviyo Lists

Inside Klaviyo, create two lists:

  1. Seed List – this will store the Warmy seed list emails.

  2. Deleted Emails List – this list will store outdated seed list emails after an update or rotation.

You will later need each list's ID. You can find the ID in the URL of the list page 🙌
