If you have a custom domain linked to your Squarespace 5 site, you can also use a custom email address. For example, if your domain is www.sampledomain.com, you can use an email address like firstname.lastname@example.org.
Squarespace doesn't host email, but you can create a custom email address with Google Workspace. This gives you free web-based email that works just like Gmail. To learn more, visit Setting up Google Workspace for Squarespace 5.
Custom email addresses work with Squarespace domains and third-party domains.
