Custom e-mail template shows raw html

Question

I created an e-mail template like this:

email_templates.xml

<?xml version="1.0"?>
  <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../Email/etc/email_templates.xsd">
  <template id="send_email_delivery_confirmation" label="Email Form" file="email_confirmation.html" type="text" module="Namespace_Module" area="frontend"/>
</config>

email_confirmation.html

<h1>Hello</h1>
<table>
  <tr>
    <td>Hello</td>
    <td>Again</td>
  </tr>
</table>

the problem is, when i open the email, the html tag not rendred at all, so it shows the html tag inside the email content:

Answer 1

Change file type type="text" to html in email_templates.xml.
