Hello there,
Good Day!!
We’re here to assist you.
The unsubscribe add-on works for both logged-in users and guest users.The only difference is that logged-in users can also unsubscribe to the product through their Myaccount page at anytime, but guest users can unsubscribe only through their email link.
Note: By considering WordPress norms, we should not promote or enclose our add-on details here. For more details, you can contact us through our website, or you can refer to our plugin’s description page on WordPress for our listed extensions.
Thanks.
