Open tracking works in a very similar way to the click tracking. When enabled, we'll insert a small image into the footer of any HTML e-mails you send out through AppMail. When this image is loaded by the recipient, it will be logged as a view and you'll be notified with a webhook.
From the activity page for a message, you'll be able to see each view along with the IP address & user agent that was used to view the message.
We've also added a number of other features which affect both click & view tracking.
- You can now enable/disable click and/or view tracking independently by changing the settings on your tracking domains.
- The list of messages includes an "Opened" label which tells you if a message has been viewed or any link in it has been clicked.
