How to Mail Merge and Add Attachments

More often than not, the message you send to people will be included in the body of your email. However, there may be certain times when you need to send an attachment to multiple recipients. If you find yourself wondering how to mail merge and add attachments, you’ll need to follow these steps:

Step 1: Download the GMass Google Extension

Step 2: Add Your Attachment File(s) to Your Google Drive

After you’ve added the GMass extension to Chrome, you’ll then need to make sure the files you want to attach to your email have been added to your Google Drive.

Step 3: Set Up Your Google Sheet for Mail Merge

When getting ready to do a mail merge with GMass, you’ll need to open a new Google Sheet and format it correctly.

The first row of your sheet should contain information such as:

  • First Name
  • Last Name
  • Email Address
  • Company
  • And so forth

This will open a drop-down menu of the various Google Sheet files you have, and you’ll need to click on the one you want to use.

Step 5: Compose Your Message

Click on the Compose button in Gmail and put together the email you want to send. For any of the fields that will be populated by the information included in the Google Sheet, such as name, leave those spaces blank.

Don’t forget to add your attachment!

Step 6: Click on the GMass Button to Send Your Mail Merge

After you’ve composed the email you want to send, you’ll then need to click on the GMass button, which should be at the top on the right-hand side.

If prompted, choose the Google Sheet from the drop-down menu.

The information will then be added to your emails, and the messages will be sent out immediately or based on your schedule.
