Problems receiving messages on Wordpress / hosting provider Hostinger

Dear all,

I am experiencing problems using my email accounts with Zoho as sign up and contact form point on my website (built with Wordpress and hosting provider Hostinger).

I have 5 email address in total with Zoho and none of them are working to receive messages from my webpage. 

Can someone please assist?

Thanks,

Alex
