Add function `changeStatus($newStatus)`, which will be reposnsible for changing status of user, and inside handle sending email aswell. — Yupik, Mar 08 '18 at 06:55
Use function `changeStatus($newStatus)` (which you need to write) to change user statuses. Inside this function you can send email to user after saving his status. — Yupik, Mar 08 '18 at 07:06

You can use afterSave($insert,$changedAttributes) to check for changed attributes and send the email.

According to the DOCS $changedAttributes parameter has old values of attributes that had changed and were saved. You can use this parameter to take action based on the changes made for example send an email when the password had changed or implement audit trail that tracks all the changes. $changedAttributes gives you the old attribute values while the active record ($this) has already the new, updated values.

public function afterSave( $insert , $changedAttributes ) {

    if ( !$insert && isset ( $changedAttributes['status'] ) ) {
        $this->sendEmail ();
    }
    return parent::afterSave ( $insert , $changedAttributes );
}

private function sendEmail() {
    //your code to email
}

public function afterSave($insert, $changedAttributes){
    if (!$insert && array_key_exists('status_id', $changedAttributes) && $this->status_id != $changedAttributes['status_id']){
        $this->sendEmail();
    }
    return parent::afterSave($insert, $changedAttributes);
}

private function sendEmail() {
    //your code to email
}

The best way to check is an attribute has changed afterSave(). See Note in this answer
