Add mail merge to google sheets

Mail merge is a powerful feature that allows you to automate the process of sending personalized emails to a large number of recipients. While Google Sheets doesn't have a built-in mail merge feature, you can use a combination of Google Sheets, Google Apps Script, and Gmail to achieve similar results. Here's a step-by-step guide to help you add mail merge to Google Sheets:

Step 1: Prepare your data

Create a Google Sheet with the following columns:

• Recipient Email
• Name
• Subject
• Body (the text you want to include in the email)
• Attachments (optional)

Populate the sheet with the data you want to use for the mail merge.

Step 2: Create a Google Apps Script

In your Google Sheet, go to Tools > Script editor. This will open the Google Apps Script editor.

Create a new script by clicking on the "Create" button.

Step 3: Write the script

In the script editor, paste the following code:

function sendMergedEmails() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var dataRange = sheet.getDataRange();
  var data = dataRange.getValues();
  var subject = "Your Email Subject";
  var body = "Your Email Body";

  for (var i = 1; i < data.length; i++) {
    var recipientEmail = data[i][0];
    var name = data[i][1];
    var attachment = data[i][3];

    var mailOptions = {
      to: recipientEmail,
      subject: subject,
      body: body.replace("{{name}}", name),
      attachments: attachment? [attachment] : []
    };

    GmailApp.sendEmail(mailOptions);
  }
}

This script will loop through each row in your sheet, extract the relevant data, and send an email to each recipient using Gmail.

Step 4: Configure the script

In the script editor, click on the "Deploy" button and select "Web App".

Configure the web app as follows:

• Execute as: Me
• Who has access: Anyone
• Authorized JavaScript origins: Leave blank

Click "Deploy" to deploy the web app.

Step 5: Run the script

In your Google Sheet, go to Tools > Script editor and click on the "Run" button next to the sendMergedEmails function.

The script will run and send emails to each recipient in your sheet.

Tips and Variations

• To include attachments, make sure to add the attachment file to your sheet and specify the file path in the attachment column.
• To customize the email body, use placeholders like {{name}} and replace them with the actual values from your sheet.
• To use a different email template, create a separate sheet with the template and use the getSheetByName method to retrieve the template sheet.
• To send emails in batches, modify the script to use a loop that sends a fixed number of emails at a time.

By following these steps, you can add mail merge functionality to Google Sheets using Google Apps Script and Gmail.
