I was confused also when clicking the test link, you get an preview of the mail in your browser, but the mail is not sent.
To send the mail, you need to execute the autonews() function, which is actually done from the cronjob.

Or you must make a call to the autonews() function from somewhere else. e.g. from the footer of your site.
Or make a panel whitout content and call it cronjob.
Every time a visitor comes on your site, the code is executed.
