How do I verify my website as safe if using a ready made storefront with no root directory access?

I would like to verify my website and receive a safe rating, but I am using a ready made storefront with hosting. I do not have access to the root directory (at least not that I know of). 

 

I do have meta tag forms and analytics settings forms and the like. Is there a way that I can handle the verification myself, or will I need to have my hosting company handle the process that was outlined in the email from Norton? 

 

My website is: www.simplygraciousstyle.com.

 

Help would be very much appreciated!
