Email address?

Email address?

I signed up for Zoho mail yesterday. This was to make a custom email for my website mrtobyparker.com 

I initially made my email ' hello@mrtobyparker.com

Afterwards, I thought toby@mrtobyparker.com would be a better email. 

I created that address and made it my primary. However - when I open the account it still heads itself as ' hello@mrtobyparker.com'...

I also cannot receive mail, would this be the cause of that?
