No list. As I said in the post, I had very little audience. Most of the success is due to me randomly messaging my Twitter contacts and asking for their support. I messaged ahead of time (maybe a few hours before?) just so it wasn't out of the blue. Everyone agreed. Some were already customers (I made some sales before the launch) so they left honest reviews of the product.

I think the other part of this being successful was the giveaway tweet, plus all the friends who just wanted to support me. I am really thankful they did!
