Setting up reply to email

Hi,

Is there a way to make the email to be replied to, to be the email of the person that left it's details in a lead generation form from jotform?

Yes, on the email notification settings you will be able to select the email field on your form as the reply to email address, please check this guide that will provide you more  details about setting up an email notification: https://www.jotform.com/help/25-Setting-up-Email-Notifications
