 # Roundcube Easy Unsubscribe
-Displays a small icon after the subject line when viewing an email, so you can very quickly unsubscribe.
+Displays a small icon after the subject line when viewing an email, so you can very quickly unsubscribe. Multiple icons may show as the plugin is reliant upon the `List-Unsubscribe` header. Sometimes emails use multiple i.e. one mailto: and one URL.
