Wix and Zoho Trouble: Can send but not receive email

Wix and Zoho Trouble: Can send but not receive email

I am trying pretty desperately to get Zoho to play nice with Wix, but I am not having any luck yet. So far, I can send emails successfully from Zoho, but I cannot receive them.

Here's my set up for my website:
Domain: 1&1 (Nameservers are pointed to Wix)
Host: Wix (MX records are pointed to Zoho,  as shown by the mxtoolbox)

Yet, I still cannot receive emails. Help?
