Would people use your product (or a version of your product) for free?
And then, could you package some feature to sell as a premium on top of the free version that would make people convert?
Either way, do you track your conversion channels to see if you attract views and how it transforms at each step? (how many people notice your product, how many look into it, how many try it [0 here if I understand])
How do you promote it (other than cold emails)?
