I purchased anarchitecture.io from Google Domains, and pointed it to a Google Cloud Compute instance Apache server by adding an A record with the IP address of the server.
I also set that domain to "Use custom name servers" and set them to the following addresses.
ns-cloud-b1.googledomains.com
ns-cloud-b2.googledomains.com
ns-cloud-b3.googledomains.com
ns-cloud-b4.googledomains.com
I created the email address anarchitect@anarchitecture.io with Google Workspaces. It is not receiving mail. I assume that I have to set up an MX record to point to the correct mail servers for this service. How do I set up an MX record without breaking my website? What addresses should I point to with the MX record?
