Using two fields to confirm email address

I would like to attempt to create a second field on our end user facing ticket form to have end users confirm their email address. We have many end users who input an incorrect email address, and having a second field that could halt the user from submitting a ticket until the two fields match would be great. I have not yet found a solution to this in the native Zendesk environment, but it would save our agents a lot of time.
