Hostgator <=> Zoho is setup but not recieving emails, able to send the mails

Hello,

I have purchased my domain in GoDaddy.in and hosting in Hostgator.

Initially before setting up host-gator everything was fine as I did configured MX with GoDaddy. IN/OUT email was tested successfully.

Now, I purchased Hostgator service and trying to configure the email and I'm not receiving any mails but luckily I am able to send the mails. 

Need help in MX / email configuration.

1. Do I need to setup something in  GoDaddy as my domain is there. 
2. Host-Gator any changes required? I already added mx records over here. 


Thanks,
