Install the BetterMerge Add-on for Google Sheets

The BetterMerge Google Sheets add-on brings mail merge capabilities directly into your spreadsheets. Work with your contact lists and launch campaigns without leaving Google Sheets—perfect for quick sends and users who prefer the familiar Sheets interface.

This guide walks you through installing the add-on from the Google Workspace Marketplace and getting it set up in minutes.

Sign in to your Google account and open Google Sheets in your web browser.

Navigate to the menu and select Extensions > Add-ons > Get add-ons.

In the Google Workspace Marketplace, type BetterMerge in the search bar. Locate the BetterMerge add-on in the search results and click on it.

Click the Install button and confirm by clicking CONTINUE when prompted.

Choose the Google account where you want to install the add-on. Then, click Continue to proceed.

Review the requested permissions and click Allow to grant access. Finally, click Done to complete the authorization.

Close the Google Workspace Marketplace popup window by clicking the X icon.

Access the add-on from the Extensions menu. Go to Extensions > BetterMerge > Open Dashboard.

The BetterMerge interface will open in a modal window inside Google Sheets, giving you access to all campaign features without leaving your spreadsheet.

The BetterMerge add-on provides the full functionality of the web dashboard, including:

✅ Create and manage campaigns – Complete campaign setup and configuration

✅ Select any Google Sheet – Choose contact lists from any of your Google Sheets

✅ Compose email templates – Rich Text and HTML editors available

✅ Add merge tags – Personalize emails with data from your sheets

✅ Configure tracking – Enable opens, clicks, and unsubscribe tracking

✅ Set up delivery automation – Control sending speed, daily limits, and time windows

✅ View analytics – Monitor campaign performance and engagement metrics

The add-on and web dashboard are the same application with identical features. The only difference is where they appear:

Choose based on your workflow: Use the add-on when you’re already working in Google Sheets, or use the web dashboard for a full-screen experience with more workspace.

1. Refresh your sheet – Close and reopen the Google Sheet
2. Check installation – Go to Extensions > Add-ons > Manage add-ons to verify it’s installed
3. Reinstall if needed – Remove and reinstall from the Workspace Marketplace

• Use an admin account – If you’re on a Google Workspace domain, your admin may need to approve the add-on first
• Check browser settings – Allow pop-ups from sheets.google.com
• Try incognito mode – Sometimes browser extensions interfere with authorization

1. Clear browser cache and cookies
2. Revoke and reauthorize – Go to Google Account Permissions and remove BetterMerge, then reinstall
3. Check third-party app access – Ensure Less secure app access isn’t blocking it

• Check sheet size – Large sheets (10,000+ rows) can slow performance
• Reduce add-ons – Too many add-ons running simultaneously can cause issues
• Try the web dashboard – For better performance with large contact lists
