It's possible to create custom notification emails and confirmation emails. To do this, go to your 'Settings' page > 'Emails and Actions', then edit or add a new notification email. Finally, select the 'Custom Message' option under 'Content'. Enter your custom message in the Message window and save your changes.
Use Your Form Fields
You can also pull over fields from your form into your custom message. To do so, drag-and-drop fields from the Form Fields Panel on the right-hand side of the screen into the body of your message. You can also use the message editor to insert images, links, tables, bulleted lists, etc.?
