How do I change the e-mail to our e-mail address?

Also, how do I brand responses from ME and not from Jotform?  

Thank you! 

Can you please tell us what email address you're referring to? Is this the email address of your account or the email address listed to your recipient of the notification?

If this is the notification recipient's email, please follow the guide below.

Also, how do I brand responses from ME and not from Jotform?

If you want to send the autoresponder from your custom email or from (ME) then you need SMTP.
