use lucky wheel with already logged in users?

We have an employee portal. Users must sign in before they can see the site or your product. So for the optin we don’t need or want employees to enter their email address (or name).

The prize we want to give are something we call “Bucks”. Bucks are a coupon employees redeem to get a bonus in the paycheck.

Can we do these things with your product?

1. Auto fill the Name and Email instead of the employee filling the fields? Could we use “{user:user_email}” for example?
2. Send the prize to the winner directly from WordPress without using a a mail service (MailChimp)?
3. Use your tool without woocommerce?
