subscribe adn unsubscribe

And If User subscribes then how to send default to confirm massage?

>can you send documentation for subscribing and unsubscribe mail?

Is anyone even reading these anymore? Can anyone explain how to add an unsubscribe link via shortcode or other method?

I found this old post: https://www.ads-software.com/support/topic/unsubscribe-page-6/

…However when I check the settings page there is no option anywhere for unsubscribe URL. *sigh*

Can anyone help?
