How to track when someone opens an email attachment

⚠️If you'd like to track PDFs we've a feature designed specifically 
  for that purpose. This FAQ explains how it works

Mailtrack can alert you when someone opens an email attachment. Here’s how:

Step1: Upload your file to Google Drive

1. On your computer, go to drive.google.com.
2. At the top left, click New > File Upload.
3. Choose the file you want to upload.

Step 2: Attach your file to a new message in Gmail

1. On your computer, open Gmail in a browser that has Mailtrack installed.
2. At the top left, click Compose.
3. Click Google Drive .
4. Select the file you want to attach.
5. At the bottom of the page, choose to send the file as a drive link*.
6. Click Insert.

*The file needs to be sent as a link. If you attach the file as you do normally Mailtrack won’t be able to track when it’s opened.

Step 3: Send your email

At the bottom of the compose window, click Send.

How to tell that an attachment has been opened

 Mailtrack has a feature called email click tracking, which tracks links in your emails. 

This means, when you add your attachment as a Google Drive link, Mailtrack can track the link and alert you when the recipient clicks on it (and opens the attachment).
