Employees and industry is there for us to learn who our customers/users are. This is a new type of service, and we need information on who are target audience are, because we frankly don't know that yet. These values are optional to fill in, though. Should we be more informative, maybe, and tell people that we will absolutely not under any circumstances give out information about them to a third party - would that reassure you?
Finally, your confirmation email might have been delayed as there was a DNS issue yesterday that caused outgoing email to be queued for a while. Apologies about that too and thank you for the feedback. It's very nice of you to give it even though you weren't happy with the service. Negative (but constructive) feedback is the most valuable of all for us.
I went through your registration process, and got nothing. Very disappointing - the type of thing that will make me never look at your website again and scoff about it to my friends should they bring it up.
And a couple other nits:
1) Your registration page where I choose my plan type is not intuitive. Maybe it's because green is not a good color to call attention to stuff.
2) Your Register and Cancel buttons should be different colors. I clicked the wrong one and had to redo my registration.
3) Don't ask for number of employees and industry. They're not required and they will hurt your conversion rate slightly. And it indicates to me you might sell my data.
