How to send email notification/autoresponder base on submitter's selections using conditions?

Is there a way to automate the process and send people who filled out the form a personalised confirmation email? I would also have different categories of personalised confirmation emails, depending on the answers people give.  

Yes, it would be possible for you to send different emails depending on the selection of your form submitters on your form.

I would suggest you check this guide, How-to-Send-Email-Based-on-Selection, and if you have questions, please feel free to get back to us and we will be glad to help you further.

Thank you.
