Hi Bob, unfortunately, this is not a feature of Unbounce. While Unbounce does have an email notification feature, it is meant to be used to notify the owner of the Unbounce account or whoever is supposed to receive the form submissions rather than notify the person filling out the form.

The best way to send a confirmation email would be to use a seperate email automation tool and just connect it to Unbounce. Some popular options that work well with Unbounce are:

HubSpot

Mailchimp 

ActiveCampaign

Campaign Monitor

AWeber

You can also connect pretty much any email automation platform you want via Zapier if there is not a direct integration already working with Unbounce.

If you need something quick and free, I believe Mailchimp still has a free plan for smaller accounts. But personally, if you want my recommendation, ActiveCampaign is the best tool in the list for this.
