shortcode [eme_unsubform template_id=45]

Hi Francky

I use a subscription and unsubscription page with the shortcode mentioned in the subject. 
When you indicate your email and validate the captcha and the form, the system indicates that it has sent an email with a link. But in fact there is no mail that is sent.
You should be able to test on the link page. 
Thanks in advance for your help.
Frédéric.
