Is there a way that they can receive an email with the form details they submitted?

I can't seem to find how the person who submits the form is able to receive a confirmation email with the form details that they submitted from our site.

I found out that I can manually 'reply' to their submission by going to 'submissions' and replying to the submitted form, but is there not an automatic way of doing this?

I can't keep track of which submissions I 'replied' to and we are looking for an automated way of achieving this.

Thanks,

Ps. I created a custom Thank You page and it redirects them there after submitting but that's it.
