how to send custom email no template in magento2?

Question

In magento2 send email with contact module use:

$transport = $this->_transportBuilder
                ->setTemplateIdentifier($this->scopeConfig->getValue(self::XML_PATH_EMAIL_TEMPLATE, $storeScope))
                ->setTemplateOptions(
                    [
                        'area' => \Magento\Backend\App\Area\FrontNameResolver::AREA_CODE,
                        'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID,
                    ]
                )
                ->setTemplateVars(['data' => $postObject])
                ->setFrom($this->scopeConfig->getValue(self::XML_PATH_EMAIL_SENDER, $storeScope))
                ->addTo($this->scopeConfig->getValue(self::XML_PATH_EMAIL_RECIPIENT, $storeScope))
                ->setReplyTo($post['email'])
                ->getTransport();
$transport->sendMessage();  

So i have create custom send email it not have template. but i don't know how do send email with transportBuilder is true.

            )
   [body] => {{template config_path="design/email/header_template"}}
              {{depend Magento Commerce}} Magento Commerce {{/depend}}
                Name:   ABC
                Email:  abc@gmail.com
                Subject:    Magento Commerce

 [type] => text/html
  [attachments] =>

How do i can send email with $myData use transportBuilder. Many thank!!

Answer 1

You need to create etc/email_templates.xml add below code

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Email:etc/email_templates.xsd">
    <template id="myemail_email_template" label="My Label" file="myemail.html" type="text" module="Modulename_Namespace" area="frontend"/>
</config>

Now you need to add file in your module at view/frontend/email/myemail.html

<!--@subject Promopoup@-->
{{trans "My var: %myVar" myVar=$data.myvar}}

myemail.html is declared in etc/email_templates.xml

Now mail sending code as below:

                $emailTemplateVariables = array();
                $emailTempVariables['myvar'] = $myvar;

                $senderName = 'test';

                $senderEmail = 'sender@test.com';

                $postObject = new \Magento\Framework\DataObject();
                $postObject->setData($emailTempVariables);

                $sender = [
                            'name' => $senderName,
                            'email' => $senderEmail,
                            ];

                $transport = $this->_transportBuilder->setTemplateIdentifier('myemail_email_template')
                ->setTemplateOptions(['area' => \Magento\Framework\App\Area::AREA_FRONTEND, 'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID])
                ->setTemplateVars(['data' => $postObject])
                ->setFrom($sender)
                ->addTo($email)
                ->setReplyTo($senderEmail)            
                ->getTransport();               
                $transport->sendMessage();

Answer 2

Original question was about not using template (as I got it) but I'm not sure. Best practice I assume is to use email template.

Here is an example of my extension which sends emails every day (cronjob isn't included)

registration.php

<?php

    \Magento\Framework\Component\ComponentRegistrar::register(
        \Magento\Framework\Component\ComponentRegistrar::MODULE,
        'ImaginationMedia_ReportSender',
        __DIR__
    );

etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="ImaginationMedia_ReportSender" setup_version="1.1.0" />
</config>

etc/email_templates.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Email:etc/email_templates.xsd">
    <template id="daily_status_template"
              label="Daily Sales by ImaginationMedia"
              file="daily_status_template.html" type="html"
              module="ImaginationMedia_ReportSender" area="frontend"/>
</config>

etc/adminhtml/routes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="admin">
        <route id="reportsender" frontName="reportsender">
            <module name="ImaginationMedia_ReportSender" />
        </route>
    </router>
</config>

view/frontend/email/daily_status_template.html

<!--@subject {{trans "Sales Report from Our Client"}} @-->

<h3>Report from {{var data.report_date|raw}}</h3>

<p><b>Number of orders:</b> {{var data.orders_count|raw}}</p>
<p><b>Items count:</b> {{var data.order_items_count|raw}}</p>
<p><b>Average items per order:</b> {{var data.avg_items|raw}}</p>

Model/ReportSend.php

<?php

    namespace ImaginationMedia\ReportSender\Model;

    use Magento\Framework\Mail\Template\TransportBuilder;

    class ReportSend {

        public function __construct(
            TransportBuilder $transportBuilder,
        ) {
            $this->transportBuilder = $transportBuilder;
        }

        public function execute() {
            $report = [
                'report_date' => date("j F Y", strtotime('-1 day')),
                'orders_count' => rand(1, 10),
                'order_items_count' => rand(1, 10),
                'avg_items' => rand(1, 10)
            ];

            $postObject = new \Magento\Framework\DataObject();
            $postObject->setData($report);

            $transport = $this->transportBuilder
                ->setTemplateIdentifier('daily_status_template')
                ->setTemplateOptions(['area' => \Magento\Framework\App\Area::AREA_FRONTEND, 'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID])
                ->setTemplateVars(['data' => $postObject])
                ->setFrom(['name' => 'Robot','email' => 'robot@server.com'])
                ->addTo(['fred@server.com', 'otherguy@server.com'])
                ->getTransport();
            $transport->sendMessage();
        }
    }

Controller/Adminhtml/ReportSender.php

<?php

    namespace ImaginationMedia\ReportSender\Controller\Adminhtml\ReportSender;

    use Magento\Backend\App\Action\Context;
    use ImaginationMedia\ReportSender\Model\ReportSend;

    class Index extends \Magento\Backend\App\Action {

        public function __construct(
            Context $context,
            ReportSend $reportSend
        ) {
            parent::__construct($context);
            $this->reportSend = $reportSend;
        }

        public function execute() {
            $this->reportSend->execute();
            echo 'Email sent!';
        }
    }
