Goal is to be able to email a video link to a potential client. Then be able to tell whether or not the client watched the video...how long client watched for etc.

Youtube offers this with analytics but it seems to be hit or miss. For example we sent a video link to client in another state. We know for sure they watched the video from beginning to end. Click/view was never recorded by youtube.

Looking for other services or other analytic apps that work with youtube. Anything else out there?
