not receiving emails at all

Dear Zoho,

Our emails are not receiving emails at all, when I tried to send an email to my zoho mail using my Gmail it said that it was sent but it didn't appear in my zoho mail inbox at all, I think it has been like this for 3 days I am not sure. 

domain: ifmsa-jo.org
you can contact me through this email too: moh.zaidan98@gmail.com .

I need help ASAP as we have alot of online work during this period of the year, 

Thank you so much,
