Hello Seattle Web Group,
I would suggest you to test the functionality offered by our user registration widget, as it offers nearly identical options of registering a user, and sending an email to him/her on registration, where the email contains a link that the user needs to click in order to confirm his/her account. If this does not suit exactly the use case scenario you want to implement, please let us know so we can advise you further.
All the best,
the Telerik team
