Sending emails one by one is inefficient when the message is mostly the same. Bulk email using Google Sheets lets you send personalised emails at scale using your existing Gmail account—for free. There’s no paid software involved, and the setup works fully inside Google Sheets and Gmail.

Google provides a built-in Mail Merge using Apps Script that connects Google Sheets with Gmail to automate this process.

What Is Bulk Email Using Google Sheets?

Bulk email using Google Sheets means sending multiple emails automatically while personalising each message using spreadsheet data.

You write one email template and use placeholders such as:

“Hi {{Name}}, thanks for registering for {{Event}}.”

Google Sheets replaces these placeholders for each recipient and sends the emails one by one.

What Does the Google Apps Script Mail Merge Do?

Google Apps Script is part of Google Workspace. Google provides an official Mail Merge sample that does the following:

• Reads recipient details from a Google Sheet
• Replaces placeholders in the email content
• Sends emails automatically through Gmail
• Helps track sent emails to avoid duplicates

This approach works fully within Google’s ecosystem, which is why it’s a practical free option for small to medium outreach.

How Bulk Email Using Google Sheets Works

At a high level, the process is simple:

• Create a Google Sheet with columns like Email, Name, and Status
• Write one email template using placeholders
• Add the Mail Merge script via Extensions → Apps Script
• Run the script to send emails automatically

Emails are sent from your Gmail account using data from each row in the sheet.

How to Use Bulk Email Using Google Sheets (Practically)

To use bulk email using Google Sheets effectively:

• Be clear about why you are sending the email
• Keep the sheet clean and organised
• Use consistent placeholder names
• Test with a few emails before sending to everyone
• Use UTM links if you want to track clicks from emails

This method works best for planned, thoughtful outreach rather than mass blasting.

Common Use Cases

Bulk email using Google Sheets is useful when the message is similar but needs personalisation:

• Event invitations
  

  “Hi {{Name}}, you’re invited to our workshop on {{Date}}.”

• Follow-ups and updates
  

  “Thanks for attending {{Event}}. Here’s what’s next.”

• Announcements and newsletters
  One format, changing recipient lists.
• Outreach and introductions
  Structured communication without manual effort.

Important Sending Limits (Read This)

When using the Google Apps Script Mail Merge with a standard Gmail account, the safe sending limit is 100 emails per day.

To stay within limits:

• Do not exceed 100 emails per day
• Split large lists across multiple days
• Avoid spam-like subject lines
• Do not resend the same message repeatedly in one day

Staying within this limit helps avoid temporary Gmail restrictions and improves delivery reliability.

Final Thought

Bulk email using Google Sheets is not about sending more emails—it’s about saving time while keeping communication personal and organised. Because it uses Google Sheets, Apps Script, and Gmail, it’s a genuinely free approach for small to medium outreach.

If you already use Google Sheets and Gmail, this is one of the simplest and most effective automations you can start with.
