Look Their are two ways to manage the DNS at GODADDY or any other domain registator
1. Use the name server of domain registator:- If you are using the name server of domain registator in that case you can use A, CNAME, MX and various other kinds of records to point out at your hosting provider and email services provider.
2. Use the name server of hosting provider:- If you enter the name server of hosting provider at domain registator in that case you don’t need to do anything else.
Now what i suggest you to do is if your hosting and and email services provider are different then use the name server of godaddy and point the A record toward the hosting provider and point the MX record toward the email services provider else simplly point the NS toward the hosting provider.
I know everything about DNS you can let me know if you need any help.
