Are there any guides for setting up Email Autoresponder and Thank-You page?

Also if you have any links on best tips and set up of form autoresponders and thank you pages that would be great too. 

If you want to receive an email notification every time your form gets successfully submitted, you can set up a notification email in your form. To learn how to, please check this guide: https://www.jotform.com/help/25-Setting-Up-Email-Notifications
