+Email helper functions
+======================
+
+:doc:`Email Helper <../helpers/email_helper>` only has two functions
+
+ - :php:func:`valid_email()`
+ - :php:func:`send_email()`
+
+Both of them are now aliases for PHP's native ``filter_var()`` and ``mail()`` functions, respectively.
+Therefore the :doc:`Email Helper <../helpers/email_helper>` altogether is being deprecated and
+is scheduled for removal in CodeIgniter 3.1+.
+
+.. note:: These functions are still available, but you're strongly encouraged to remove their usage
+	sooner rather than later.
