Adding/Showing Site url

There is no such option, you can simply add it to the bottom of your emails

I understand that much…I am trying to use this in a multisite system to where I do not have to do it for hundreds of sites……..just wanted to know if you might have a coding option, not a feature in the plug in. As your unsubscribe code does this but it adds the unsubscribe link to the site url…….thanks for your reply
