As the joker says ' if you are good at something don't offer it free', and I completely agree to that as a business, but as a customer ( and definitely someone who is not early adopter) I would find paying for a service like this a little over the top, and there could be many like me. So the target audience is limited right now for SaneBox unless it shifts to the enterprise segment, that is an area where it can make a bigger dent.
