I have tried all the 3 ways you mentioned for email setting up, domain verification.
site is tangybox.com, it is hosted on AWS and domain is on Bigrock.in
1. added CNAME, error:
There are no CNAME Records found for your domain.
2. added TXT, error:
There are no TXT Records found for your domain.
And its not like I am checking instantly, but I have waited for over 1 day for each. Its been 3 days. please sort it out.
