Better Email Notification
With a very simple setup, you can now use the email notification you receive to reply directly to the person who submitted the response.
First make sure that your form actually asks for an email address, and that this question has a validation of type ‘email’ (this can be done in the Form Builder).
Then, in the form properties page, in the ‘upon response’ section, set the reply-to option. The drop-down menu will list the form fields of type ‘email’. Choose the appropriate one and save.

That’s it. On your next email, you’ll be able to hit ‘reply’. The email used will be the one posted by the respondent (if you see ‘report @ formassembly . com’ instead, your setup is probably not right).
