Email Verification Within Contact Form

Heya!

So I've been receiveding emails from potential clients using the built in Contact form. However on a couple of occasions the client has typed in their email incorrectly. I would like add an email verification as part of the block, where the client can type their email a second time and notifies the customer if the email does not match.

If anyone could help me with this i'd be much appreciated.

I'm also looking for help to set this up
