Form email notifications not working

I recently just put together my website and I set up form notifications to send an email to hello@kthusdesigns.com but it’s not coming through. I’ve added a secondary @gmail to the form notifications and that one seems to be getting them.

@kthusdesigns The domain kthusdesigns.com doesn’t appear to have any MX records.

Do you have any set?
