How to fix Magento 1.9 Email sending problem

In the latest Magento versions, all emails are being sent via CRON job.
Every email will be queued and sent will depend on the set interval.

By default, Magento has already set CRON jobs at 

System -> Configuration -> Advanced -> System -> Advanced -> Cron

If the CRON job is not working properly, please follow the following steps to send instant emails.

Copy Template.php file from 

app -> code -> core -> Mage -> Core -> Model -> Email

Create folder structure like 

app -> code -> local ->  Mage -> Core -> Model -> Email

Paste Template.php file in an Email folder

Open Template.php file and go to line number 407 or search for the following code 

 if ($this->hasQueue() && $this->getQueue() instanceof Mage_Core_Model_Email_Queue) {

Replace above code with following

 if (!($this->hasQueue()) && $this->getQueue() instanceof Mage_Core_Model_Email_Queue) {

This trick works perfectly on Magento Version 1.9.2.0
