When you put your email address on this popup (module bonnewsletter), it says subscribed, but really don’t works. User didn’t receive email.
I think perhaps this module is linked with ps_emailsubscription (on this module you can set the option to send confirmation email on subscribe).
But if you use the Subscription default email box, you don’t receive the confirmation email and appears this error:
Error - The following e-mail template is missing: newsletter_conf
Well, we need to be able to subscribe throught the popup and throught the Newsletter footer email box, and user receive confirmation email correctly.
