I am trying to connect Zoho mail to my domain (hosted on Namecheap).  I have added the Zoho CNAME to my Namecheap records and wanted to make sure I had done everything correctly before migrating.  As I have also connected Namecheap to my Gmail address (via Namecheap's free email forwarding service), I am worried the migration will affect my Gmail, but this may not be the case.  

I simply want to be able to use the multiple email addresses I created via Zoho ( x@mydomain.com - where mydomain is hosted on Namecheap).  Do I need to migrate?  Please forgive my naivete if this question begs an obvious answer.

Thank you very much in advance for your assistance,

Kat
