I had a client ring me about the issues with not receiving emails, I have done a test email to their accounts and get:
Address not found
550 5.1.1 The email account that you tried to reach does not exist.
The domain is builtbycavetto co uk
Email: mark@
Rachael@
Both emails do not work:
Thank you for the reply, the client does not have admin access to google workspace, and the company that was managing the website has now stopped trading.
