                <tr>
                    <td valign="top" colspan="5">
                        <h1 style="font-size:22px; font-weight:normal; line-height:22px; margin:0 0 11px 0;">Hello Admin,</h1>
                    </td>
                </tr>
                <tr>
                    <td valign="top" colspan="5">
                        <p style="border:1px solid #E0E0E0; font-size:12px; line-height:16px; margin:0; padding:13px 18px; background:#F9F9F9;">You Have Received New Query As Bellow.<p>

                </tr>
                <tr>
                    <td valign="top" colspan="5">
                        <p style="border:1px solid #E0E0E0; font-size:12px; line-height:16px; margin:0; padding:13px 18px; background:#F9F9F9;">Customer Name : <strong>{{var customerName}}</strong></td>
                </tr>
                <tr>
                    <td valign="top" colspan="5">
                        <p style="border:1px solid #E0E0E0; font-size:12px; line-height:16px; margin:0; padding:13px 18px; background:#F9F9F9;">Customer Email : <strong>{{var customerEmail}}</strong></td>
                </tr>
                <tr>
                    <td valign="top" colspan="5">
                        <p style="border:1px solid #E0E0E0; font-size:12px; line-height:16px; margin:0; padding:13px 18px; background:#F9F9F9;">Customer Comment : <strong>{{var customerComment}}</strong></td>
                </tr>
                <tr>
                    <td valign="top" colspan="5">
                        <p style="border:1px solid #E0E0E0; font-size:12px; line-height:16px; margin:0; padding:13px 18px; background:#F9F9F9; text-align:center;"><strong>Thank you.</strong></td>
                </tr>
            </table>
        </td>
    </tr>
</table>
</div>
</body>

Step 3: Now the template is ready and we will do the code for sending mail.

Go to your controller file

app\code\Vendor\Extension\Controller\Index\Index.php

Add the below-mentioned code

<?php
namespace Vendor\Extension\Controller\Index;

use Magento\Framework\App\Action\Context;
use Magento\Store\Model\StoreManagerInterface;
use Magento\Framework\Mail\Template\TransportBuilder;
use Magento\Framework\Translate\Inline\StateInterface;

class Index extends \Magento\Framework\App\Action\Action
{
    protected $transportBuilder;
    protected $storeManager;
    protected $inlineTranslation;
    protected $state;

    public function __construct(
        Context $context,
        StoreManagerInterface $storeManager,
        TransportBuilder $transportBuilder,
        StateInterface $state)
    {
        $this->transportBuilder = $transportBuilder;
        $this->storeManager = $storeManager;
        $this->inlineTranslation = $state;
        parent::__construct($context);
    }
    public function execute()
    {        
        $templateId = 'your_email_template_id'; // template id
        $fromEmail = 'admin@gmail.com';  // sender Email id
        $toEmail = 'test.magecomp@gmail.com'; // receiver email id
        $subject = 'your_dynamic_subject'; // Dynamic subject
        try
        {
            // template variables pass here
            $templateVars = [
                'subject' => $subject,
                'customerName' => 'Test',
                'customerEmail' => 'Magecomp',
                'customerComment' => 'Test Comment'
            ];
 
            $storeId = $this->storeManager->getStore()->getId();
            $this->inlineTranslation->suspend();
 
            $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
            $templateOptions = [
                'area' => \Magento\Framework\App\Area::AREA_FRONTEND,
                'store' => $storeId
            ];
            
            $transport = $this->transportBuilder->setTemplateIdentifier($templateId, $storeScope)
                ->setTemplateOptions($templateOptions)
                ->setTemplateVars($templateVars)
                ->setFrom($fromEmail)
                ->addTo($toEmail)
                ->getTransport();
            $transport->sendMessage();
            $this->inlineTranslation->resume();
            $this->messageManager->addSuccessMessage(__('Your Email Sent successfully'));
            $this->_redirect('*/*/');
        }
        catch (\Exception $e)
        {
            $this->inlineTranslation->resume();
            $this->messageManager->addErrorMessage(__('We can\'t process your request' . $e->getMessage()));
            $this->_redirect('*/*/');
        }
    }
}
