Email to Users waiting to be notified when this product is back in stock

VIRTUEMART 3.0.9 JOOMLA 3.4.3
on the backend in the status page of a product:

I can see the people on the list of users with valid emails. When I click on the send email button it says it was sent but noone receives anything. I´ve tried without the template with no luck.

Any help is much appreciated. Thanks!
