How to send Observer Response via mail?

[Aveeva]

My observer :

<?php
    class Gta_MerchantNotification_Model_Observer
    {
        public function merchantremainder($Observer)
        {
            $order = $Observer->getEvent()->getOrder();
            $order_details = $order->getAllVisibleItems();
            foreach ($order_details as $list) {
                $incrementid = $order->getIncrementId();
                $sku = $list->getsku();
                $name = $list->getName();
                $price = $list->getPrice();
                $Qty = $list->getQtyOrdered();


                Mage::log("Id : $incrementid, Sku : $sku, Product name : $name, Price : $price, Qty Ordered : $Qty",  null, 'merchant.log', true);

            }
        }
}

?>

output :

Id : 100000083, Sku : #14, Product name : The Step F1004 Step Workout System, Price : 28.5, Qty Ordered : 1

How to send mail?

[Rahul Gupta]

@Aveeva you can use the mail function for sending mail.

<?php
$body = "Hi there, here is some plaintext body content";
$mail = Mage::getModel('core/email');
$mail->setToName('John Customer');
$mail->setToEmail('customer@email.com');
$mail->setBody($body);
$mail->setSubject('The Subject');
$mail->setFromEmail('yourstore@url.com');
$mail->setFromName("Your Name");
$mail->setType('text');// You can use 'html' or 'text'

try {
    $mail->send();
    Mage::getSingleton('core/session')->addSuccess('Your request has been sent');
    $this->_redirect('');
}
catch (Exception $e) {
    Mage::getSingleton('core/session')->addError('Unable to send.');
    $this->_redirect('');
}

Thanks
