Gutenberg forms

Hello again.

I am starting to use Guttenberg forms. But unlike other forms I have tried, I can’t get a personal email when a user makes an action (such as subscribe or contact me).
I´ve setup the email notification from the email builder area.
(by envelop icon in the block tool bar). What can be the problem?
THANKS
