[Plugin: WP Responder] unsubscribe form on blog?

hello, I need advice or solutions – how to make a form to unsubscribe? I know there is a link in every email, but I need the form on the site. You type your e-mail and will be discharged or transferred to the page you normally get in an email (unsubscribe page.) I saw a function that checks whether an e-mail address is in the database, I saw the place where the generated link in the email, but I’m not a php programmer and I don’t know how to get this form. Can anyone help me? / / Sorry for my english – translator …
