Sendspark supports two kinds of variables for personalizing videos: text variables and voice (AI voice cloning) variables. Text variables — first name, company name, email, and a custom field — personalize the video landing page template. AI voice cloning currently supports only the first name variable, used once at the very beginning of the dynamic video.
