While Klaviyo does not have a built-in integration with WisePops, you can still integrate your WisePops account with Klaviyo. This is possible via an integration available through WisePops.
Before you get started, you must already have existing lists in your Klaviyo account. You will also be asked to enter your Klaviyo API key. Here, you'll need to generate a Private API Key in Klaviyo instead of using your public API key / Site ID. You can generate a Private API Key by navigating to Account > Settings > API Keys or head to our article on managing your account's API keys for more information.
Sync a WisePops Form to Klaviyo
1. Log into your WisePops account and open or create a popup with a sign-up form. Find the signup box and click Edit.
2. In the Edit window, you will see an option to Sync your pop-up.
Click on this option and you will see Klaviyo under the Email Platforms section.
3. Enter the Private API Key that you previously generated.
4. From the Choose Your List dropdown menu, choose the list where you would like new subscribers to join.
Then, new subscribers opting-in through your WisePops form will automatically sync to Klaviyo.
