Sync New Subscribers from Google Sheets to MailerLite without Duplicates

This n8n workflow provides a complete solution to automate the syncing of new subscribers from Google Sheets to MailerLite. It reads contact data from a specified Google Sheet, checks each email against existing MailerLite subscribers, and only adds new ones to prevent duplicates. Fields like email, first_name, last_name, company, country, and group_id are seamlessly transferred.

Key benefits include maintaining clean email lists, saving time on manual imports, reducing bounce rates from duplicates, and ensuring accurate audience segmentation via groups. It's particularly useful for marketing teams, small business owners, and community managers who rely on Google Sheets for lead capture.

Use cases span email marketing automation, such as syncing webinar signups, newsletter subscribers, or customer leads from forms. In healthcare contexts like medical records outreach, it ensures compliant list management without redundant entries. Setup is straightforward: connect Google Sheets and MailerLite credentials, specify sheet details and group IDs, then activate for scheduled or manual runs.
