magento2 send email programmatically without template

Question

I want to send custom email programmatically without any template.

In magento 1, I used below script to do same thing.

$mail = Mage::getModel('core/email');
$mail->setToName('xxx');
$mail->settoemail('[email protected]');
$mail->setBody($html);
$mail->setSubject('Test email : '.$fieldss['o']);
$mail->setfromemail('[email protected]');
$mail->setType('html');// YOu can use Html or text as Mail format
$mail->setBodyHTML($html);  // your content or message
try{ 
    $mail->send();
}catch (Exception $e) {
    echo $e->getMessage();exit;
}

Here, In magento 2 I used below code but it gives error.

$objectManager = $this->getObjectManager();
$transport = $objectManager->get('Magento\Framework\Mail\Template\TransportBuilder');
$transport->addTo('[email protected]', 'Hiren Shah');
//$transport->settoemail('[email protected]');
//$transport->setBody($html);
$transport->setSubject('Test email : '.$fieldss['o']);
$transport->setFrom('[email protected]');
$transport->setType('html');// YOu can use Html or text as Mail format
$transport->setBodyHTML($html);  // your content or message
$transport->getTransport();
try { 
    $transport->sendMessage();
} catch (Exception $e) {
    echo $e->getMessage();exit;
}

But this gives me error Call to undefined method Magento\Framework\Mail\Template\TransportBuilder\Interceptor::setSubject()

How to send custom email without template? Please give me code sample.

Answer 1

Magento 2: The simplest way I found to send a plain text - use Zend1 mail

    $to = ['[email protected]', '[email protected]'];
    $email = new \Zend_Mail();
    $email->setSubject("Feedback email");
    $email->setBodyText($body);
    $email->setFrom($from, $nameFrom);
    $email->addTo($to, $nameTo);
    $email->send();

Send email programmatically without email template, code is tested in Magento 2.4

/**
 * @var \Magento\Framework\Mail\MessageInterfaceFactory
 */
protected $messageInterfaceFactory;

/**
 * @var \Magento\Framework\Mail\TransportInterfaceFactory
 */
protected $mailTransportFactory;

/**
 * @param \Magento\Framework\Mail\MessageInterfaceFactory $messageInterfaceFactory
 * @param \Magento\Framework\Mail\TransportInterfaceFactory $mailTransportFactory
 */
public function __construct(
    \Magento\Framework\Mail\MessageInterfaceFactory $messageInterfaceFactory,
    \Magento\Framework\Mail\TransportInterfaceFactory $mailTransportFactory
) {
    $this->messageInterfaceFacory = $messageInterfaceFactory;
    $this->mailTransportFactory = $mailTransportFactory;
}

public function execute()
{
    $from = '[email protected]';
    $to = '[email protected]';
    $subject = "email subject";
    $emailHtml = "<h1>Test Email</h1>";

    try {
        $message = $this->messageInterfaceFactory->create();
        $message->setFromAddress($from);
        $message->addTo($to);
        $message->setSubject($subject);
        $message->setBodyHtml($emailHtml);
        $transport = $this->mailTransportFactory->create(['message' => $message]);
        $transport->sendMessage();

    } catch (\Exception $e) {
        echo "error=>".$e->getMessage();
    }
}

You can send mail using Zend_Mail() function.

$firstname = "xxx";
$lastname = "yyyyyy";

// Send Mail functionality starts from here 
$from = "[email protected]";
$nameFrom = "From Name";
$to = "[email protected]";
$nameTo = "To Name";
$body = "
<div>
    <b>".$firstname."</b>
    <i>".$lastname."</i>
</div>";

$email = new \Zend_Mail();
$email->setSubject("Email Subject"); 
$email->setBodyHtml($body);     // use it to send html data
//$email->setBodyText($body);   // use it to send simple text data
$email->setFrom($from, $nameFrom);
$email->addTo($to, $nameTo);
$email->send();
