All ThankView videos auto-play when a recipient clicks to view their video. Most browsers prevent video from auto-playing if there is sound. In order to guarantee that the video auto-plays the video begins muted.
All recipients are able to click the "Tap to Unmute" button on the upper left side of the video to hear the sound. This is a common practice of many sites that incorporate video.
Currently, there is no capability to have individual videos to be unmuted. Our research suggests that View rates increase when the videos auto-play.
