mj-raw
Displays raw HTML that is not going to be parsed by the MJML engine. Anything left inside this tag should be raw, responsive HTML.
If placed inside <mj-head>, its content will be added at the end of the <head>.
<mjml>
<mj-body>
<mj-raw>
<!-- Your content goes here -->
</mj-raw>
</mj-body>
</mjml>
If you use mj-raw to add templating language, and use the minify option, you might get a Parsing error, especially when using the < character. You can tell the minifier to ignore some content by wrapping it between two <!-- htmlmin:ignore --> tags.
<mjml>
<mj-body>
<mj-raw>
<!-- htmlmin:ignore -->{% if foo < 5 %}<!-- htmlmin:ignore -->
</mj-raw>
<!-- Some mjml section -->
<mj-raw>
{% endif %}
</mj-raw>
</mj-body>
</mjml>
