Having to provide an email just to see what this is all about is an enormous barrier of entry tantamount to directly asking for my credit card number. At least buy me lunch first. Even if I were in the market for this, I would be reluctant. Given that I don't think I am, I will not expose myself to potential spam or upselling, and your website doesn't even try to convince me otherwise (that I actually need your product) I hope this comes across as constructive criticism.
