Bulk WhatsApp Messages from Google Sheets Automation

This n8n workflow enables businesses to send bulk WhatsApp messages efficiently by pulling recipient data and message content from a Google Sheet. It triggers every minute to check for pending rows (where status is empty), limits processing to 2 messages per run to respect API limits, cleans phone numbers by removing non-digits, and dispatches pre-approved templated messages, including optional image headers. Upon success, it updates the sheet to mark rows as 'Sent', providing full visibility into campaign progress.

Ideal for marketing teams running outreach campaigns, customer support for notifications, or any business needing scalable WhatsApp communication without coding. Benefits include time savings on manual messaging, compliance with rate limits, easy data management via Sheets, and real-time status tracking to monitor delivery rates and failures.

Key features: Scheduled polling for continuous operation, batch limiting for reliability, number sanitization for error-free sending, support for rich media templates, and seamless two-way integration between Google Sheets and WhatsApp Business Cloud. This no-code solution scales for high-volume use while minimizing API costs and errors.
