Reports: tracking opens and unsubscribes
Every time you send a newsletter it is added as a separate "report" in the new Reports view. That means that you can very easily track what newsletter is sent when, to who and how successful that newsletter was. When ccNewsletter detects that you did not complete sending the newsletter to all subscribers, for whatever reason, there is an orange warning and a smart "Continue" button that will continue sending the newsletter exactly where you stopped until you get that nice little green label you see at "My first newsletter"!
With "Opens" you see how many times your newsletters are opened. And "Unsubs." shows you how many people unsubscribed from ccNewsletter after having received that specific newsletter. Let's hope that doesn't happen to often!
We want to expand the reporting functionality in the future, so please let us know if you have any more things you would like us to add to reports!
Technical explanation, or "Why is it not working?"
The reports functionality works via a file called "tracker.php" located at /components/com_ccnewsletter/helpers/tracker.php. To use the Reports functionality you need to be sure the file can be accessed directly by your newsletter subscribers. Some Joomla! security extensions (Akeeba AdminTools, RSFireWall) and custom htaccess files block direct access to PHP files that are not part of Joomla's core. You will need to add the above file as an exception to those extensions/custom htaccess files. Please refer to the documentation of the security product you are using.
