 ## How it works
 
-When a form submission is created, a listener checks the form's MailerLite settings.

Make sure a queue worker is running (or use the `sync` queue driver) for subscribers to be created.
+When a form submission is created, a listener checks the form's MailerLite settings. If syncing is enabled and a field mapping is present, a queued job sends the subscriber — with the mapped fields, the selected group, and the submitter's IP address (which MailerLite uses as a consent and spam signal) — to MailerLite. Make sure a queue worker is running (or use the `sync` queue driver) for subscribers to be created.
