The problem is

The email confirmation link that is sent when I use Freeform mailing list Parameter does not work

But when I test using the ee mailing list sign up it works

any ideas?

Moved to the Modules discussion.  Since this problem is specific to Freeform, you’ll need to contact Solspace for assistance.  Thank you and have a great weekend!
