LonNaylor knows what he is talking about!
It is not only the quality of the video but how much it persuades you to buy.
I have been persuaded like that.
I haven't put video on my actual site yet (I don't know why, I'm just slacking I guess) but I do use video email and I have had tremendous results with it because people aren't used to seeing it yet.
Just 2 days ago, I had someone actually call me on the phone about 2 minutes after she saw my vmail and she was ready to join my business.
