How would I send email when the new entity is created?

I haven't used this module yet but I have built similar webform_to_node modules that create a node based on webform submissions and providing that this module works, you would simply add a webform handler as an email so that when the form is submitted, the appropriate email is sent.

@jayvolk, I tested my suggestion that you just create a normal email web handler using the WebForm Settings UI and it does indeed work.

I think this can be closed as works as designed.
