Preview an email as different contacts

I've created an email which uses a variety of different dynamic information pulling from the contact record. Eg something like... Qualification: {Qualification Status} Expiry Date: {Qualification Expiry} {Comment 1} {Comment 2} {Comment3} When I preview the email, or send a test, these fields are blank. Is there a way I can view the email as if I were different contacts, so I can sense check my content? Thanks
