Not receiving emails from WordPress

Not receiving emails from WordPress

Hello,

After setting up my account, I tested it with myemail@gmail.com and it worked fine.

Tested zoho mail with myemail@gmail.com

But when I tried to update my Zoho email (contact@mydomain.com.ng) in my WordPress admin area, I waited for a long time but I didn't receive the email in my Zoho mail account and I created the email purposely for WordPress.

Tested zoho mail with WP but not working

Can you check, please? I can't seem to figure out what the problem was.

Thank you.
