It works great and I get the double opt in email when testing, but I get redirected to a new url
https://manage.kmail-lists.com/subscriptions/subscribe?a=ACCOUNTID&g=LISTID
With the message
{"show_double_opt_in_page":true}
Is there some sort of page I need to setup that will be displayed here? Or how do I prevent that redirect?
