Unable to receive wordpress emails to Gsuite

Hi,

I’m unable to receive any email from wordpress to my gsuite address.
Google team have confirmed the issue is with the sender. Even their report confirms the same:
“No messages found. Please contact the sender for further investigation.”

What tests I’ve done:
? changed wp admin email from Settings > General. Says confirmation pending.
? changed wp admin email from phpmyadmin
? changed wp admin email from ….com/wp-admin/options.php.
Now it does show my wp admin email address is the gsuite email address e.g. [email protected]
But I’m still not receiving any email from WordPress.

Please help me!
