Changing my domains to point to zoho

Changing my domains to point to zoho

I have my domain registered through IX Webhosting.com.  I went into the control panel and entered "zmverify.zoho.com" in the nameserver1 field.  My domain hosting requires a 2nd nameserver.  I do not see a 2nd nameserver on the zoho site.

What am I doing wrong.  My domain is registered via ToCows through IXWebhosting.com.

I am a novice and do not know how to get zoho setup to receive emails from my domain......keithswebdesign.com.

Thanks KS
