Sync Squarespace Newsletter Signups to Mailchimp via Google Sheets

This n8n workflow captures newsletter signups from Squarespace forms stored in Google Sheets and automatically adds them as new contacts to a specified Mailchimp audience. It addresses Squarespace's limitation where native Mailchimp integration only works with new, empty audiences, enabling seamless synchronization to existing lists. Users can trigger it manually or schedule it for ongoing automation, ensuring no signups are missed.

Key benefits include time savings by eliminating manual data entry, improved email list growth, and reliable data transfer with fields like Submitted On, Email Address, and Name. It's ideal for marketers managing Squarespace sites who use Mailchimp for campaigns, supporting continuous list building without technical headaches.

Setup involves connecting your Squarespace newsletter block to Google Drive to create a submission spreadsheet, then configuring Google Sheets and Mailchimp credentials in n8n. Clone the provided template sheet for instant compatibility, select your Mailchimp audience, and run. Perfect for e-commerce sites, blogs, or any Squarespace user scaling email marketing.
