I am having issues receiving emails for sales@browdanwindows.com.

I have set up the MX records so I am slightly confused why this is happening? 

Delivery to the following recipient failed permanently:

      info@browdanwindows.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain  browdanwindows.com  by  smtp.secureserver.net . [68.178.213.203].

The error that the other server returned was:
550 5.1.1 < info@browdanwindows.com > Recipient not found.  < http://x.co/irbounce >

Why is this happening?
