Im trying to set up an autoresponder email

After someone submits the form, I want an automated email to be sent to them to inform them of the next steps. Is this possible?

Yes, this is possible with JotForm's autoresponder email feature. Simply, when you set up an autoresponder email into your form, autoresponder email will be sent to form submitter's email address after form submission.

Could you please check this guides which might be helpful for your needs:
