Where should I email my domain verification proof?

Where should I email my domain verification proof?

The "contact us" form does not work for me, it returns an error, so I thought I'd post here. 
I would like to use my domain with zoho, and I need to verify my domain.  
I cannot edit the CNAME or TXT records for my domain, as I've added the nameservers for  Microsoft Office 365. 
I took a screenshot of my domain control page and will gladly email it to you.  I saw that this is possible from "  In case you are unable to verify the domain, even after adding the CNAME/ HTML, send us the screen shot of the DNS Manager page, providing the domain expiry and registration details."

Thanks!
