Should transferring the target of my domain effect my email service?

Should transferring the target of my domain effect my email service?

I've had my domain set up with zoho for some time, with no problems. Sunday evening/Monday morning I changed the nameservers in my registrar (godaddy) to point to new servers. Tuesday evening I began experiencing trouble with my zoho mail. Do I need to do any re-authentication of the domain since I changed the nameservers and thus the server it points to?

Thanks!
