I changed web hosts, updated mx, but zoho email with my domain not working?

Hopefully someone can help out. I got an email account with zoho with a domain a purchased from wordpress.com. I decided to switch over to wordpress.org and host at bluehost.com.

My site is up and running again and the DNS is all switched over, but my email didn't work. I thought maybe it was the mx, so I changed that and it still doesn't work. What else do I need to do?

Sorry if this is a ridiculous question, I am not very techy.
