Refresh List is an email verification and list-cleaning service. The Google Workspace Marketplace listing is coming soon.Refresh List for Google Sheets™ helps marketers, agencies, sales teams, recruiters, and data teams inspect and verify email lists, monitor progress, and import results into a separate sheet while keeping the original data unchanged.
Built to keep the selection, progress, and results easy to understand.
Install Refresh List for Google Sheets™ from the Google Workspace Marketplace after approval.
Open a Google Sheet™ containing an email column with a header row.
Select the email column, including its header, then open Extensions → Refresh List → Open Tools.
Connect securely using Refresh List. You never enter your Refresh List password inside the add-on.
Refresh List checks the selected range, identifies empty or duplicate entries, and prepares the verification job.
Choose available trial checks or paid credits and start verification.
The add-on displays progress and can resume an active job if the sidebar is closed or the spreadsheet is reopened.
When verification is complete, Refresh List creates a separate “Refresh List Results” sheet. The original email column remains unchanged.
Depending on the verification response, your results may include:
Refresh List creates a separate results sheet so you can review verification outcomes without overwriting your original list.
Your source sheet remains the record you started with, while the results sheet makes the next campaign decision easier to review.
Use this workflow to keep each verification run organized and reviewable.
Refresh List processes only the email range selected by you. The add-on does not read unrelated spreadsheets, Drive files, images, or personal content.
Refresh List does not generate, upload, analyze, store, or distribute images. It does not use Google APIs for AI-generated content, facial recognition, image generation, or AI-generated non-consensual intimate imagery (NCII).
