About this solution
Automatically create draft email replies to feedback from Google Forms. This
solution focuses on course feedback from students, but you can apply it to any
use case for which you receive feedback via Google Forms.

How it works
The script installs an event-driven trigger that runs each time a user submits a
form. With each form submission, the script creates an email draft in Gmail. The
email is addressed to the person who submitted the form and includes the form
responses and a generic thank-you message. You can edit the email before you
send it.
