I changed my domain's nameservers to Wix from Homestead and now cannot get email

I changed my nameservers on one of my domains to point to a site I'm building using Wix. I had no idea this would affect my EMAIL. I haven't received any business emails in four days (shocking). Homestead says it will disrupt service when you change nameservers - I assumed this meant website service, not email service. I have a new primary and secondary nameserver that point to Wix. Do I have to add an additional one for mail or something? Any advice you can provide would be greatly appreciated.
