You can integrate AcyMailing with Contact Enhanced so that when a user submits a form, this user is also subscribed to one or several AcyMailing Lists. Contact Enhanced uses the AcyMailing API, so it will work with all AcyMailing Versions (including Starter).
Select Components → Contact Enhanced → Form Fields from the drop-down menu on the back-end of your Joomla! installation, then Select AcyMailing from the Form Field's Type Select list;
Choose a category for your Form Field (CF), then Save the changes in order to load the AcyMailing Form Fields Specific parameters.
The Acymailing parameters will be displayed After the Form Field is saved. All Parameters are optional
The image on the right is an example of how AcyMailing CF is be displayed on a page. In this case it is displaying all lists.
With Contact Enhanced you can add many other Form Fields types, but for the purposes of this example there are only 3 (Name, Email, AcyMailing);
