You can automatically generate and send a personalized Sendspark video whenever a contact is added to a Klaviyo list. Set up a video campaign in Sendspark, build a Klaviyo flow triggered by “Added to List” with a time delay and an HTML email block holding the embed code, then create a Sendspark automation triggered by Klaviyo’s “Added profiles to list” to generate each contact’s video.

​
Key takeaways

  • The workflow spans three setups: a Sendspark video campaign, a Klaviyo flow, and a Sendspark automation.
  • In Klaviyo, trigger the flow on Added to List, add a time delay (e.g., 1 day) so Sendspark can generate the video, and paste the embed code into an HTML block (not a text block).
  • In Sendspark, the automation triggers on Klaviyo → Added profiles to list, uses the same list, then runs a Create a Dynamic Video step with the contact data mapped.
  • Optionally add a Data Cropping step to derive a company domain from a business email for the video background; API calls may take 5-10 minutes to complete.

​

Frequently asked questions

The delay (for example, 1 day) gives Sendspark time to generate the personalized video before the email goes out, so the recipient receives a completed video rather than a placeholder.
Use the HTML block, not the text block. Delete all the default HTML in the block, then paste the embed code you copied from Sendspark’s Share campaign step.
Add a Data Cropping step before the Dynamic Video step. Select Email as the input, crop using the ”@” character, and choose “Crop to the End” (e.g., dan@senspark.com → senspark.com). Then map the result to Background URL. This works mainly for business emails, not Gmail or Outlook addresses.
API calls may take 5-10 minutes. Check the automation history in Sendspark for statuses like Added profiles to list, Data cropping, and Create dynamic video, confirm the video was processed in the campaign, then run a self-test by adding your own email to the Klaviyo list and triggering the flow.
