Email Authentication on Google Domains / Squarespace

Google Domains was acquired by Squarespace in 2023. If your domain was with Google Domains, it's now managed at domains.squarespace.com. DNS setup is similar but the interface has changed.

Open domains.squarespace.com → your domain → DNS. Google Workspace MX presets may appear if you're on Google — still verify TXT records manually.
