Entity form submission sending email I'm working on entity form using the module "eform" in D8.

I would like it to send email when the user submits a form. It was done using some other modules rules and entity rules, but since "entity rules" is not released yet in D8, I couldn't find a way to send submission email.
Is there any module to make it possible or should I create a custom module to do that?
I've asked the question multiple times. It appears that we need to wait for Rules. For the time-being, I'm using the built-in drupal contact form + contact_storage module for form. It's not the best, but it works.
