// template id, 通常在email_templates.xml定义。如果是在后台加的email template，需要换成template的记录ID，例如90
$identifier = 'contact_email_email_template';
/* @var \Magento\Framework\Mail\TemplateInterface $templateFactory */
$templateFactory = $this->_objectManager->create(
'Magento\Framework\Mail\TemplateInterface',
['data' => ['template_id' => $identifier]]

// 模板变量，取决于phtml或后台email template的内容
$dataObject = new \Magento\Framework\DataObject();
$dataObject->setData('name', 'william');
// 决定模板变量取值区域，例如像{{layout}}这样的标签，如果取不到值可以试试把area设为frontend
$templateFactory->setOptions([
'area' => \Magento\Backend\App\Area\FrontNameResolver::AREA_CODE,
'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID
]);
$templateFactory->setVars(['data' => $dataObject]);
return $templateFactory->processTemplate();获取所有邮件模板的位置(powershell)
ls -Recurse vendor\magento\*\ | where {$_.Name -eq "email_templates.xml"} | foreach {
$modulePath = $_.Directory.Parent.FullName
$emailTemplatesXml = (get-content $_)
$emailTemplatesXml.config.template | foreach {
$file = $_.GetAttribute("file")
$area = $_.GetAttribute("area").toString()

}
}关于模板变量
虽然通过email_templates.xml找到邮件模板很容易，但模板中使用的变量是PHP端提供的，模板变量只能在发送邮件的时候定义，所以如果要调整模板变量往往不太好找。以下列出自带组件含模板变量定义部分的代码位置
vendor/magento/module-sales/Model/Order/Email/Sender/*.php
vendor/magento/module-customer/Model/EmailNotification.php
vendor/magento/module-send-friend/Model/SendFriend.php有趣的是order相关的email有event可以追加模板变量，例如email_order_set_template_vars_before，但并不是所有官方开发的邮件变量都有event可用。
官方的邮件变量定义代码都在Model里，但第三方组件就未必。其实也并不难找，只要对组件全代码搜索->setTemplateVars(，就可以很容易找到。
