You emailed me just because I semi-filled in your form? I didn't even click SUBMIT! o_O
Why would you assume that if I semi-filled a form I would probably go ahead and register? Maybe I don't want to register at this very moment?
Did you even consider that my NOT submitting the form was a conscious decision? Maybe I realized halfway through filling the form that my skill-set wasn't good enough to make me want to sign up now? Or my finances wouldn't allow me to maintain an account on your platform after six months? Or maybe, just maybe, I just didn't want to sign up right now?
Why would you take my email ID from a non-submit-clicked form and NOT tell me that you had taken it? Why? o_O
Even worse, why would you email me asking 'did I forget to take my cloud'? How do I know you are not going to spam me with your promotional offers in the future? How do Iknow you are not going to sell (or worse, 'inadvertently leak') my email address to some third party?
