Send a Tracking email automatically

[yohha]

I’m using on my magento 1.9.1 shipping extensions from DPD.
DPD is not sending Tracking Information when order is complete, i need to go for each order to shipment and to send manually the "Send Tracking Information" we have 50-40 packages a day and it take us a lot of time to send the shipment mail.
is there any option to it should send automatically the "Send Tracking Information"??
UPDATE: i found a code
if($shipment){ if(!$shipment->getEmailSent()){ $shipment->sendEmail(true); $shipment->setEmailSent(true); $shipment->save(); } }
add the code in /app/code/community/DPD/Shipping/Model/Adminhtml/Dpdgrid.php after line 93
