Unsubscribe button please
This service is awesome and user will be warned if they are pwned.
But the registration confirmation email says "...and you can unsubscribe at any time if you don't want the notifications."
Please, make an unsubscribe button. I can't find any unsubscribe button or form on the website or in the email.
Feature already exists
There is already an unsubscribe button at the bottom of every email sent.
Edit: Just to clarify, the original verification email does not have an unsubscribe button, but it also says "If you don't want to receive any future breach notifications, just ignore this email". All subsequent notifications have an unsubscribe link.
