If you might happened to use Cloudflare (vPanel integration) then you can’t receive email since it blocks incoming email.
You may want to use Cloudflare directly and update your nameservers and you are responsible for configuring your DNS correctly.

More information about not receiving email can be found here:

It might be a problem with that the contact messages are cannot be received (like @UnknownLolz
said), but it’s also possible that the messages were not sent correctly.
