WordPress form verification email

I need to create a simple WordPress webform capable of verifying submitted email addresses. The submission process must be as streamlined as possible, so breaking this into a two-step problem where the user first signs up for an account on the site (email verification) before submitting the form data, for example, is out of the question.

The approach that seems obvious to me is to store the submitted forms in a database and send the submitter an automated email with a hyperlink containing a random token which, when clicked, updates the database to record that the submitted form's email address is bona fide.

Is there a well-supported WordPress plugin that can do this, or achieve the same result through some other strategy?
