As of Joomla 3.9, Joomla introduced an action logging system. This system provides an infrastructure to create an audit log of activity performed on a website and can be fine-tuned to the site admin's preferences.

Contact Enhanced PRO Package (version 3.9.1 and newer) has a plugin to integrate with Joomla's User Actions Log Component and it is very simple to enable the integration. Just follow these simple two steps:

  1. Go to Extensions → Plugins, search for Action Log - Contact Enhanced and enable it.
  2. Navigate to Users → User Actions Log → Options button and select Contact Enhanced among the Events To Log.
