Learn more about how JungleMail tracking works.
How tracking works for email opens
When you send an email through JungleMail, a small invisible graphics, also known as a web beacon, is inserted at the bottom of the HTML body of your emails. This graphic is unique per email, recipient, and campaign. When someone opens the email and views the images within it, the graphic is downloaded from the service, triggering the individual tracking mechanisms and registering this as an email open on your campaign report. Automated replies (e.g., out-of-office messages) usually do not download this graphic and thus don't count as opens.
Note: although the tracker graphic is a widely accepted standard for email open tracking, it has some drawbacks that you should know. Since this method requires a hidden graphic to be embedded in your email code, it will not work with plain text campaigns. Similarly, if your subscribers or their email client have opted to prevent displaying images in the email body, email opens will not be tracked.
How tracking works for link clicks
When tracking is enabled, JungleMail replaces all links in the email to the URL of the tracking page. In this replaced URL, some data (e.g., group email job ID, recipient ID for JungleMail) is encoded so that JungleMail Web Service could sort the data correctly. When the user clicks the link, the process below takes place:
1. The link takes the user to the JungleMail Tracker Web Part.
2. JungleMail Tracker Web Part takes the URL ID and passes it to JungleMail Web Service.
3. JungleMail Web Service uses the URL ID to find the user in the JungleMail Tracker Actions List (on your main site collection) and records an action (link click).
4. JungleMail locates the primary destination (the actual URL) and gives it to the JungleMail Web Part to redirect the recipient to the actual URL.
Note: if you use JungleMail Enterprise with enabled SQL mode, all campaign links and actions (link clicks, opens, and unsubscribes) are saved in the JungleMail SQL Database tables instead of SharePoint lists.
For JungleMail to track opens and clicks of external users or internal users connecting via external or mobile devices, you will need to place JungleMail Tracker Web Part and JungleMail Subscription Web Part on an external SharePoint site collection with anonymous access. In other words, tracking requires anonymous access to the empty site collection where only JungleMail Tracking Web Part is stored. Please note that the actual tracking data is stored in your main (internal) site collection, which is not publicly available. Read more on how to create a site collection with anonymous access.
