I know the cancel order event order_cancel_after but how can I send cancelation e-mail to the customer when admin cancels their order from admin.

How to write a custom extension for this.

Any help would be appreciated.

Thanks in advance..!

Create an observer file in Vendor/Module/Observer/CancelOrder.php


    namespace Vendor\Module\Observer;

    use Magento\Framework\Event\ObserverInterface;
    use \Magento\Store\Model\StoreManagerInterface;
    use \Magento\Framework\Mail\Template\TransportBuilder;
    use \Magento\Framework\Translate\Inline\StateInterface;
    use Psr\Log\LoggerInterface;

    class CancelOrder implements ObserverInterface
        public function __construct(
            StoreManagerInterface $storeManager,
            \Magento\Framework\Message\ManagerInterface $messageManager,
            TransportBuilder $transportBuilder,
            LoggerInterface $logLoggerInterface,
            StateInterface $inlineTranslation
        ) {
            $this->storeManager = $storeManager;
            $this->messageManager = $messageManager;
            $this->transportBuilder = $transportBuilder;
            $this->inlineTranslation = $inlineTranslation;
            $this->logLoggerInterface = $logLoggerInterface;
        public function execute(\Magento\Framework\Event\Observer $observer)
            try {
                $order = $observer->getEvent()->getOrder();
                $custFirstname = ''; # Set customer name from order
                $custEmail = ''; # Set customer email from order
                $template_sub = ''; # Set email subject
                $sender_name = ''; # Set sender name
                $sender_email = ''; # Set sender email
                $template_content = ''; # Set email content
                $templateId = 'cancel_order_template';
                $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
                $sendFrom = $sender_email;
                $senderName = $sender_name;
                $sendTo = $custEmail;
                $transport = $this->transportBuilder
                            'area' => 'frontend',
                            'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID,
                        'template_subject' => $template_sub,
                        'customername' => $custFirstname,
                        'email_content' => $template_content,
                    ->setFrom(array('email' => $sendFrom, 'name' => $senderName))
            } catch (\Exception $e) {
