Automated Email Validity Verification and Update Workflow

This workflow automatically deduplicates and verifies the validity of email addresses in a mailing list on Google Sheets by real-time monitoring and utilizing a third-party API. The results are then updated back into the spreadsheet. This process significantly improves the quality of email data, reduces errors caused by manual checks, and is suitable for email marketing and customer relationship management, ensuring accurate communication addresses, enhancing email delivery rates, and reducing resource waste.

Automated Email Validity Verification and Update Workflow

Key Features and Highlights

This workflow automatically monitors changes in email lists within Google Sheets in real-time, performs deduplication, and invokes a third-party email verification API to check the validity and deliverability of email addresses. The verification results are then updated back into Google Sheets, enabling automated cleaning and maintenance of email data. The entire process is efficient and automated, reducing manual checks and data errors, thereby improving the accuracy of email marketing and customer management.

Core Problems Addressed

  • Duplicate email data affecting data quality and subsequent marketing effectiveness

Application Scenarios

  • Regular cleaning of customer email lists by email marketing teams to improve delivery rates

  • Any business relying on email communication to ensure the accuracy of contact addresses

Main Workflow Steps

  1. Trigger Monitoring: The Google Sheets Trigger node checks for data updates in the specified Google Sheet every minute.
  2. Email Existence Check: An If node determines whether the “Status” field for an email is empty to avoid duplicate processing.
  3. Deduplication: The Remove Duplicates node eliminates duplicate entries based on the email field.
  4. Email Verification: The HTTP Request node calls Effibotics’ email verification API to assess email validity.
  5. Result Update: Verification results are written back to the corresponding rows in Google Sheets to keep data synchronized.
