Email Deliverability Verifier: Google Sheets + Effibotics API

This n8n workflow monitors a Google Sheets document for new or updated email lists, triggering automatically on changes to row counts. It processes the data by removing duplicates based on email fields, then sends each email to the Effibotics Email Verifier API for deliverability checks, including validity, catch-all detection, and disposable email identification. Results are updated in real-time back to the original sheet, ensuring marketers always have clean, verified contact lists.

Key benefits include significant time savings on manual verification, reduced bounce rates in email campaigns, and improved deliverability scores. By integrating seamlessly with Google Sheets—no coding required—users can copy-paste email lists from templates and watch validations happen live. This eliminates the need for separate tools or spreadsheets, streamlining data hygiene for sales, marketing, and CRM teams.

Ideal use cases: Preparing email campaigns for cold outreach, cleaning lead databases before import to tools like HubSpot or Mailchimp, or maintaining ongoing list hygiene. It's particularly valuable for high-volume lists, as the workflow handles polling every minute and continues on errors for robust operation. Setup involves linking your Google Sheets OAuth and Effibotics API key, making it accessible for non-technical users.
