personalized email

personalized email

Hi,
Half an hour ago I set up a personalized email:  jimmyn@coolifedesign.com  however, it still shows:  coolifedesign@zoho.com

Is it just a delay or should I do something else to activate jimmyn@coolifedesign.com inbox?
I know that it's a basic question, but need to know the answer asap as I need to catch a flight soon.

Appreciate your help,
Thanks
