I chose to use a separate confirmation page instead of the message appearing in the place of the form. However, the subscriber is redirected to the URL but there isn’t a confirmation message. Is there a short code or something I must add into the page for it to work? What must I do to get the message to appear?
I ended up to use newsletter plugin dedicated pages (not newsletter page on wordpress) because they have the advantage to focus the user on the confirmation process. That way I avoid distractions wit sidebars, etc..
