Hey @ttouf,
Thanks for taking the time to leave a review and sorry to hear that you find most of the options only available in the PRO version.
The Lite (free) version of WP Mail SMTP is designed to provide everything you need to send emails reliably. This also includes tools and option to help with troubleshooting the setup through the debug events to ensure that email setup works as expected.
As mentioned in our plugin description, the Pro version of WP Mail SMTP provides additional features if needed. Screenshot: https://a.supportally.com/i/PzChxv
Kind regards.
