Form Emails - How 'Sender Email' option works

4. Sender Email. I thought selecting the "Reply-to-Email" does that in the recipients section. Please elaborate on the difference between that and the Sender email in the Advanced section. Also what if we want customers to be able to reply to someone? 

The 'Sender Email' option relates to the 'From:' field rather than the 'Reply-To:' field.

This option can be used if you would like to change the sender email from our default noreply@jotform.com email address to something else. We support custom senders and SMTP senders:
