I work for a school that has our website and domain on Squarespace (cornerstonecrossroads.org), and we're getting set up with Google Workspace for Education for next school year. As part of this process, we're looking into creating a subdomain that will be used specifically for student email addresses (my.cornerstonecrossroads.org).
I know that I'm able to create the rule for the subdomain within Squarespace, and that I'll need to add the Google MX record, but I'm uncertain of where the subdomain would forward to. Please advise how best to set this up. Thanks!
