not getting wordpress notification via mail

I have changed my email from:

Admin profile
Setting->General
and I added this code for from email id in functions.php

/** changing default wordpres email settings */

add_filter('wp_mail_from', 'new_mail_from');
add_filter('wp_mail_from_name', 'new_mail_from_name');

function new_mail_from($old) {
 return '[email protected]';     //I am using here client original email id
}
function new_mail_from_name($old) {
 return 'Mail from my website';
}

but I am still getting all notification of wordpress in old email id not in the new one which I have changed.

What should I do If I missed something then ask and thanks in advance…..
