Using Litmus with Klaviyo

The Litmus Extension in the Google Chrome browser integrates with Klaviyo's new editor to let you test emails, including those with personalized, dynamic content. No need for manually copying and pasting code between tools, saving time and streamlining your email workflow.

Get started

First, install the Litmus Extension. You can then use the Litmus extension in Klaviyo when editing or previewing emails in the Campaigns or Flows area of Klaviyo.

NOTE: You must switch to the new template editor in Klaviyo. The classic editor is not supported.

Using the Litmus Extension in Klaviyo

1. In Klaviyo, navigate to a campaign.
2. Select Next, then use the breadcrumb (...) menu to the right of the Edit button to select Preview email.

3. In the Preview email view, click the Chrome extension in your browser to open the Litmus sidebar.

4. In the sidebar, view email previews across your default list of clients and devices configured within your Litmus account, and other key elements of a Litmus test such as link functionality check, analytics tracking code inclusion, image blocking, and loading speed. Click on any preview thumbnail to view the full-sized preview. 
5. Use the Open in Litmus button at the bottom of the sidebar to view the email in the Litmus platform, run a complete and thorough pre-send Litmus Test, and take advantage of additional collaboration and email analysis tools
