Hello @anon5704455,
currently, you can set up an assignee who will be notified: Create Forms in Asana | Product Guide • Asana Product Guide
You can also work with rules to add more collaborators to the task when a form submission is received. And then via rules you can also send comments so they are notified.
In case you want to customize the form submission message you could do so with the help of
Flowsana
In case you want to trigger an email to be sent to random people then you would have to set up something in Zapier for example.
I hope that helps
