Postmark template: dynamic variable with html processed as text instead of html

Question

I have a Postmark email template where the dynamic variable contains html. However, it processes that html as plain text.

More concretely, I have the code below. The variable body is sent to the email template, however the <br><br> is displayed as text instead of that it goes to the next line.

In controller:

const body = "Hi...<br><br> Welcome to our a new episode.";
client.sendEmailWithTemplate(
    {
        TemplateAlias: process.env.POSTMARK_TEMPLATE,
        TemplateModel: {
            body: body
        },
        From: from,
        To: email,
    });

In Postmark template:

<tr>
  <td>
    1. The following includes text with a br break: {{body}}
  </td>
</tr>
<tr>
  <td>
    2. This line includes a br break directly in the template: How are you? <br> Anything new?
  </td>
</tr>

This results in an email where the br break does work on location 2 but not on location 1. On location 1 <br> <br> is displayed as text: "<br> <br>".

What am I doing wrong?

Answer 1

Postmark support provided the answer:

We normally escape HTML but you can get around that by using this syntax for the variable:

{{{body}}} or {{&body}}

The triple braces or ampersand will let you put HTML into that variable when populating your TemplateModel values.

Do you know if we can use our own HTML code in direct value of key "TextBody"? – Photosynthesis
