Connecting Klaviyo with Bouncer

Here you will find the instructions on how to connect your Klaviyo account with Bouncer, and how to import your list and export verified addresses back to Klaviyo.

With Bouncer, we’ve made the job as easy as possible. You can connect your account to Klaviyo, verify email addresses through our simple and intuitive system, and export all the cleaned-up data back to your platform.

In order to set up your integration, log into your Klaviyo account, click on your account name (top right corner), and go to the Account section. Then, click on the Settings button and choose API keys. You need to create an API key and copy it. Once it’s done, log into your Bouncer account, select Verify List section, and click on the Klaviyo icon in the Integrations field. Bouncer will ask you to enter the API key. When the process is finished, your integration is set!

Verifying your list and sending your campaign.

Step 1

Open the Verify List tab and select the Klaviyo Import. Select the list that you would like to verify, and start processing it. Please remember that the maximum size of the list is 10k email addresses.

Step 2

Once the verification is complete, you can export the clean data back to Klaviyo by clicking on the export button in the row of completed verification.

Step 3

When you choose Export, you see the option to remove a specific group of email addresses (e.g., undeliverable, risky: disposable, etc.). As soon as the export of the data is completed, you can start creating your campaign!


  • Deliverable
    The recipient's email provider has confirmed that the email address exists, it is safe to send.
  • Risky
    The email address may result in a bounce or low engagement. Risky addresses: Accept All, Full Mailbox, or Disposable.
  • Undeliverable
    The address is either syntactically incorrect or does not exist.
  • Unknown
    We were unable to receive a response from the email provider. The credits for such verification will not be deducted from your balance. We never charge you for the email addresses with this status.
Pro-tip #1:
You can find more information regarding statuses in the Terminology section on your Bouncer account.
