This workflow captures Squarespace newsletter signups in a Google Sheet and automatically creates new Mailchimp contacts in the selected audience.
It overcomes the limitation in Squarespace’s native Mailchimp integration, which only supports new, empty audiences.
You can trigger the workflow manually or schedule it for continuous synchronization.
