Not receiving emails

Not receiving emails


I have recently set up a Zoho mail account and developed a domain name email.  I have made all the recommended changes to the MX records and CNAME to verify the domain name,  yet when I send test emails I do not receive them. I made the MX changes around two days ago now,  so it should have registered.

I would really appreciate any advice anyone can offer. 
Thanks
Alicia
