The “created with Sendspark” text appears on a LinkedIn thumbnail because the landing page header was left empty during dynamic campaign setup. Whatever you type in that header shows on the thumbnail, so add text like “Hey First Name” to personalize it. To remove the sendspark.com line, connect a custom domain in your workspace settings.

Key takeaways

  • Whatever you put in the landing page header appears on the LinkedIn thumbnail; an empty header is what produces the “created with Sendspark” legend.
  • Add personalization such as “Hey First Name” to the header so the lead’s name shows in the thumbnail.
  • Connect a custom domain in your workspace settings to remove the sendspark.com line at the bottom of the thumbnail.
  • LinkedIn caches thumbnail images, so regenerate the video for a new link if you’ve already shared it and need the updated thumbnail to appear.
