No Email after changing DNS NS

No Email after changing DNS NS

My domain is registered through AWS.  I had my website hosted there and had ZOHO mail MX settings all working for a while.  

Yesterday changed the hosting of my website to a different company, and changed the NS setting in my Hosted Zone from AWS to point to my new Hosting,

My Hosted Zone details are still on AWS. 

I kept everything else the same.  Just changed the NS to ns1.dns-parking.com

Today, I do not have email working.  

Do I need to keep the NS pointing to AWS? 

How would I make it so Zoho Mail is not effected.  

I just changed the NS listing back to AWS--hopefully it will start working today.
